Slow reaction - denying things that use AoO?

So the unchained rogue talent Slow Reactions denies enemies their attacks of opportunity. Can they still use their AoOs to do other stuff? Like the Swashbuckler's Parry and Ripost, which uses up an AoO.

Oh, and by the way, things lasting 1 round ends at the beginning of my next round, right?

No and yes.

They can expend their uses of AoO for other things, but cannot make an AoO.
