Backcourt violation or not?

I believe the situation that will cause the most problems, because of the clarification of when a throwin ends, is with momentum causing a player who catches a ball with one foot in the front court and momentum carries them into the back court. While legal if during a throwin, if the ball has been deflected (in a manner that is considered a legal touch) and A1 gains control of the ball with one foot in the front court and momentum takes them into the back court - at that point there is a violation. That is because the consideration to allow a players momentum to legally take them into the back court only exists during a throwin. If the ball has been legally touched the throwin is over and that consideration no longer exists.

But in reference to the original posters question - there would be no violation.

but that is just my reading on the rules.

Actually, the misunderstanding evident in this post is worse than even JR thought.

Bannind, please allow to me to attempt to help you a bit. You are missing a key point.
The three exceptions to the backcourt violation are all for AIRBORNE players. In order to be eligible for one of the exceptions, the player must receive the ball while BOTH feet are off the floor. If one foot is touching the court at the time when the player catches the ball, then none of the exceptions can apply and the play is governed by the normal rule.

So in addition to the new clarification making it crystal clear that the play posted in the OP is indeed a backcourt violation (and I had always called it that way), what you posted above and I highlighted in red is also a violation and has been for a long time. There is even a case book play stating exactly such. Here it is:

9.9.1 SITUATION A: A1 catches the throw-in pass with one foot on the floor in A's frontcourt and the other foot not touching the floor. The non-pivot foot then comes down in A's backcourt. RULING: Violation. Team control is established in A's frontcourt when A1 catches the throw-in pass. The violation occurs when A1 subsequently touches the backcourt with the non-pivot foot.
