There are two types of team control. While the rules are poorly written in this area, the NFHS has made its intentions clear.

Let's call them "Preliminary Team Control" and "Full Team Control". (That isn't what they're called, just what I'm calling them for the sake of discussion).

Preliminary Team Control begins when the thrower has the ball for a throwin.
Full Team Control begins when a player inbounds obtains player control.

Both end in the same way....a try is released, the other team gains control, or the ball becomes dead.

Team Control fouls are defined to happen whenever there is either....no FTs for any foul by the offense from the time they have the throwin until the time when team control is defined to end.

All other issues that depend on team control go by Full Team Control.

So, when the ball became loose on the inadvertent whistle, the throwin had ended but there was no Full Team Control. Since the throwin ended but Full Team Control had not yet been established, the resumption of play would be based on the AP arrow.

This is how we can have team control fouls on a throwin but no backcourt violation until after a player inbounds has player control.
