Backcourt violation or not?

[KGB]

On a TI from the division line, A1 releases the ball. The ball is deflected by B1 (who is pressuring the TI). The ball gets delected further into the air.

A2, jumps from his frontcourt, catches the ball in the air while over the division line and then lands in the backcourt.

Is this a violation?

Clearly prior to this season, it was not a violation.

However, this year, the TI ends when the ball is legally touched inbounds which seems to occur when B1 deflected the inbounds pass. Therefore, the TI "exception" to the backcourt violation would no longer apply.

All other criteria for a backcourt violation seem to be present.

What am I missing???????????
