pass off the backboard, into the backcourt

[silverfox]

If the official judges it to be a pass, then it would be a back court violation if the thrower or a team mate is first
to touch the ball after it enters the back court.
If he deemed if to be a shot, then no violation, no whistle.

I think this is how we explain how a shooter can be the first one to recover his own air-ball. That is , we see it as a shot and not a pass (self pass).
