Backcourt questions

Will someone clarify why the above is not a violation but *9.9.1 SITUATION D is?

In Situation D, I think it's a violation because after Team Bs deflection on the throw-in, the Team A player jumped from the frontcourt, caught it in the air & then landed in the backcourt.

If that is true would the OP sitch be a violation if after the Team A deflection, the ball was caught in the air by A after jumping from the frontcourt & landing in the backcourt?
