Backcourt/Frontcourt Interpretation

[Zoochy]

RushmoreRef, thanks for submitting my 4 questions to your state association and to Mary Struckoff at the NFHS.
I am still having a problem with her rules interpolation to Question 4.

(4) Throw-in for Team A near the division line in their front court
(Team B's backcourt). A1's throw-in is deflected by B1 who is applying
direct pressure on A1. B2 jumps from their backcourt court, catches the
ball in the air and lands first foot in the frontcourt, second foot in
the backcourt.

In this case play, the player jumps from the backcourt, secures control in the air, lands FC then BC. 9-9-3 states that for the exception, the player has to jump from the FC.
