Coming back inbounds after a save.

[bossref]

I am looking for either a better explanation
or a validation of what I use.
When a player who saves a loose ball is carried off the court because of his momemtum and wants to come back in
to play the ball....
I hear players and coaches complaining that he can't come
back in and be first to touch the ball.
I know he can and I explain his legal return this way:
"He must have SOMETHING IN & NOTHING OUT!"
and of course he must return at approximately the same
spot he left.
Anyone respond to this differently (or better)? Thanks.
