Disarming with a tailed tiefling

[Dispari Scuro]

So I'm playing with the idea of a build -- a tiefling that has disarm, and this tail:

Grasping Tail. If you have the prehensile tail racial trait, you can use your tail to grab unattended items within 5 feet as a swift action as well as to grab stowed objects carried on your person; you can hold such objects with your tail, though you cannot manipulate them with your tail (other than to put them in your hand).

So, a few questions.

1: I'm assuming if I disarm someone, I can spend a swift action and immediately pick up that item. Or does this item on the floor still count as "attended?"

2: Does this provoke? Normally picking up an item is a move action, and provokes. But this is a feat and a swift action. I don't have to bend over to do it. But I guess I might have to take my eyes off the person?

3: Greater Disarm specifies that when you disarm someone, the item lands 15 feet away in a random direction. Can I opt out of that? Obviously it's better for me if it lands at their feet, and I can just 5-foot step toward it. Or do I just go flailing around wildly and throwing the item crazy far, against my own better judgment? In which case am I actually better off not taking Greater Disarm, to prevent myself from having to go chasing after the item (which would provoke)?

4: Say all the above works, I disarm a guy, and now I'm holding his sword in my tail. What does he have to do to get it back? Does he have to disarm my tail, or does he have to steal from me?

1. As long as you haven't used your swift action yet, that is correct. As soon as it leaves a person's hand, the weapon is considered unattended.

2. This one is kinda sketchy, as there are examples of swift actions and even free actions provoking (Reloading a crossbow without the Crossbow Mastery feat comes to mind...) but under a loose interpretation of RAW, let's go with no, it doesn't provoke.

3. Under RAW, you can't opt out of it, you'd be better off not taking Greater Disarm.

4. You can't steal a held object. The enemy would have to disarm you or make you drop it some other way, through paralysis, for example.

It seems odd that once you become even better at disarming people you lose control of yourself and can't just have the item drop next to them even if it would be a benefit to do so. I suppose it's written in such a way that suggests it could be mandatory, but I feel like it may be an oversight that they didn't consider that may actually be beneficial in some situations. Heck, even in normal situations you could spend a standard action to disarm and a move action to pick it up, but if you throw it 15ft away that's actually worse.

Think of it as you're now so good at disarming that you do it forcefully such that when the weapon leaves their hand, it flies further away from them. In most instances this will be a good thing since they would have to move to retrieve it.
