Backcourt violation?

[LRZ]

In the OP, we don't know from where A2 jumping into the air to catch the ball, front or back. Nonetheless, let's change the facts slightly.

A1 shoots, B1 grabs the rebound and throws a long outlet to B2 at midcourt. A2, in his/her front court, jumps, intercepts/catches the pass, and lands with one foot in his/her front court and the other in the backcourt.

If you are arguing that A2 catching the ball while airborne from the front court gives the ball front court status, so that it's a BCV when he/she lands, I don't think the rules are meant to be applied that way. One of the many unforeseen glitches in the rules, perhaps.
