A Player shall not . . .
ART.1 . . . Be the first to touch a ball after it's been in team control in the frontcourt, if he/she or a teammate last touched or was touched by said ball having frontcourt status before it went to the backcourt.
If it were written this way, player A, in the backcourt in the original scenario, is more clearly the last to touch the ball having frontcourt status and the first to touch it after it has acquired backcourt status. Violation.
That's why I alluded to the 'catches the tap' issue. not because it is a perfect analogy, but because it is precedent for having, at times, to apply two rules at once.
