Rule 9-9-1
A player shall not be the first to touch a ball after it has been in team control in the frontcourt, if he/she or a teammate last touched or was touched by the ball in the frontcourt before it went to the backcourt.
Unlike Sit 10, none of those four "inspired" situations show that Team A had control in the frontcourt. The ball may have been in the frontcourt, but Team A never established control.
