Help me understand when I get an Aoo

[Nosta]

Do you want to know something that isn't explicitly stated in the text of the SRD or the feats/stance in question?

well I have two questions

first with combat reflex and the following to feats Karmic Strike & Robilar's Gambit would I get two Aoo if my foe trys strike in melee and manages to connect with a blow?

also for thicket of blades what all do they mean by movement. moving from one square to another or any body movements down in a square I attack?
