over and back?

[SHellmueller]

Actually, I happened to see the play live, and it went like so: A1 in backcourt, running end line after made basket, throws to A2. A2 jumps from frontcourt to catch ball, lands in backcourt. It wasn't called a violation which is correct.

Mark's "thing to remember" is a very good one. However, I think the more appropriate thing here is 9.9.2, exception 1:

EXCEPTION 1: It is not a violation when after a jump ball or a throw-in, a player is the first to secure control of the ball while both feet are off the floor and he/she then returns to the floor with one or both feet in the backcourt.

Now, here's a quiz for you: Say the same play occurred but A1 had already passed the ball inbounds to A2, so the throw-in was over. Now what's your call?
