Back court questions

[BigT]

*9.9.1 SITUATION C: A1 is dribbling in his/her backcourt and throws a pass to
the frontcourt. While standing in A’s frontcourt: (a) A2 or (b) B3 touches the ball
and deflects it back to A’s backcourt. A2 recovers in the backcourt. RULING: In
(a), it is a violation. The ball was in control of A1 and Team A, and a player from
A was the last to touch the ball in frontcourt and a player of A was the first to
touch it after it returned to the back court. In (b), legal play. A Team A player was
not the last to touch the ball in the frontcourt. Team A is entitled to a new 10-second
count.

I thought you had to have player control and team control in the front court to get this over and back call. So deflecting is control? What happens if it hits his player in the back while standing in front court and comes back into backcourt and is grabbed by A3? Is that a violation?

This came from a question from a fellow official.

Any case scenarios pertaining to A1 with possession in the front court, ball slapped by B1 away from A1, touches any part of any A player and then is recovered by any A player in backcourt. Is this a violation?

Any clarification would be appreciated.

Thanks in advance
