backcourt or play on?

The interpretation already states that an A player would have to wait for the ball to hit in the backcourt before they could be the first to touch.

APG: What is the reference for this interpretation that states that team A player would have to wait for the ball to hit in the backcourt? Are you referring to something other than NFHS books? I'm not arguing, just interested.
Before I have to explain this one to a coach, I want to be able to quote chapter/verse. I was buying the party line until I couldn't find it in the casebook. I like the A-A-A analogy: If team A had team control in frontcourt, team A last touched the ball in the frontcour, and team A is first to touch in backcourt, then violation. If any one of those 3 As is a Bs, no violation. However, if there is a casebook play that contradicts this, please share.
I'm specifically referencing NFHS 12-13 books but would also like to know the reference if in another publication.
