Point of Interruption

[howie719]

I find I question if I apply the two of these correctly sometimes. Is there a simple way to keep POI and the AP straight. I understand that sometime the AP is the POI in cases where no team control exists.

Sit: A1 on fast break. B1 comes from behind and bats ball out of bounds. Coach goes nuts and has been, So I wack him prior to giving A ball for a throw in on the endline. Shoot two at other end and give A1 there throw in on endline. Did I apply the rule correctly? Is there a live ball dead ball way of looking at POI in general.
