Thrown Weapon Combat Style - False Opening

[Plerumque]

From the ACG, the Thrown Weapon combat style includes False Opening as a bonus feat that can be taken at 6th level. The feat's wording seems to assume that the user has a way of not provoking opportune attacks, but by my reading it does not strictly preclude that possibility.

False Opening wrote:

Benefit: Choose a ranged weapon or a thrown weapon. When you make a ranged attack using that weapon, you can choose to provoke an attack of opportunity from one or more opponents who threaten you. You gain a +4 dodge bonus against such attacks. An opponent that makes such an attack and misses you loses his Dexterity bonus to AC against you until the end of your turn.

I see three possibilities. Either it's unusable without the prerequisite, it provokes an extra attack of opportunity in addition to the one the aggressor would normally get, or it just provides extra benefits when an AoO is provoked from throwing within range. There may be something else I haven't considered, though. By RAW, how would it work?

I think RAW is the extra AoO thing (which can only be used if the target has Combat Reflexes or similar). It's rather obvious it was not written with an ability to skip its prereqs in mind.

Thanks for the clarification.

There is a feat in Ultimate Combat, Close-Quarter Thrower that allows you to pick a thrown weapon and not provoke in melee, it is listed as a pre-req for the feat False Opening.

The ability to ignore feat tree prerequisites does lead to some interesting combinations. For example, a natural weapon ranger skips Vital strike and takes Improved Vital Strike as his style feat at 10th level.

I'm building a two weapon throwing Slayer, and if I save on some feats that would be awesome(ly broken).

It sounds like you automatically allow the opponents to make a free attack of op on you and if they do until the next round they have no dex! mwhahahaha! Sneak attacks and easier to hit all around!
