Stalwart Defender's intercept vs grapple

[Are]

I had a situation come up in my game just now, and I'm unsure if my decision was the correct one.

One among the party went to grapple an enemy spellcaster, and her Stalwart Defender bodyguard (in a defensive stance at the time) intercepted the grapple to end up being grappled itself instead.

What I'm wondering is this: Does an attempt to grapple actually fulfill the requirements of the intercept ability?

Some relevant rules text:

Intercept:

Once a round as an immediate action, when a melee or ranged weapon would successfully strike an adjacent ally, the stalwart defender can choose to have the weapon strike him instead of the intended target. The attack automatically hits the stalwart defender, regardless his AC or any miss chance in effect, and he suffers the normal consequences of the attack.

Performing a Combat Maneuver:

When performing a combat maneuver, you must use an action appropriate to the maneuver you are attempting to perform. While many combat maneuvers can be performed as part of an attack action, full-attack action, or attack of opportunity (in place of a melee attack), others require a specific action. Unless otherwise noted, performing a combat maneuver provokes an attack of opportunity from the target of the maneuver. If you are hit by the target, you take the damage normally and apply that amount as a penalty to the attack roll to perform the maneuver. If your target is immobilized, unconscious, or otherwise incapacitated, your maneuver automatically succeeds (treat as if you rolled a natural 20 on the attack roll). If your target is stunned, you receive a +4 bonus on your attack roll to perform a combat maneuver against it.

When you attempt to perform a combat maneuver, make an attack roll and add your CMB in place of your normal attack bonus. Add any bonuses you currently have on attack rolls due to spells, feats, and other effects. These bonuses must be applicable to the weapon or attack used to perform the maneuver. The DC of this maneuver is your target's Combat Maneuver Defense. Combat maneuvers are attack rolls, so you must roll for concealment and take any other penalties that would normally apply to an attack roll.

Grapple:

As a standard action, you can attempt to grapple a foe, hindering his combat options. If you do not have Improved Grapple, grab, or a similar ability, attempting to grapple a foe provokes an attack of opportunity from the target of your maneuver. Humanoid creatures without two free hands attempting to grapple a foe take a –4 penalty on the combat maneuver roll. If successful, both you and the target gain the grappled condition (see the Appendices). If you successfully grapple a creature that is not adjacent to you, move that creature to an adjacent open space (if no space is available, your grapple fails). Although both creatures have the grappled condition, you can, as the creature that initiated the grapple, release the grapple as a free action, removing the condition from both you and the target. If you do not release the grapple, you must continue to make a check each round, as a standard action, to maintain the hold. If your target does not break the grapple, you get a +5 circumstance bonus on grapple checks made against the same target in subsequent rounds. Once you are grappling an opponent, a successful check allows you to continue grappling the foe, and also allows you to perform one of the following actions (as part of the standard action spent to maintain the grapple).

[The Crusader]

If the character initiating the grapple did so by using a weapon with the "Grab" property, or a natural attack with the "Grab" special ability, then I would say that it could be intercepted.

Otherwise it is just a combat maneuver and doesn't meet the requirements for the intercept ability. I.e. "when a melee or ranged weapon would succesfully strike..."

[Drakkiel]

Agreed with Crusader

Thank you both! I guess I overthought it. Time to make amends..

[Drakkiel]

Personally I don't see an issue with it...if you did it that way without knowing for sure and it worked out ok then I don't see a problem.

Some of the more fun things I've had happen in PF or any RPG went against the rules

Oh, there's no issue, just poor word choice on my part. What I meant was fix the situation to have the proper result (one of the benefits of PBP games!)
