Yet another backcourt question

[Rufus]

I've been reading the posts over the last couple of weeks but haven't seen this one yet so any help would be appreciated:

A1 has the ball and is established in A's frontcourt (both feet and ball in A's frontcourt). A1 attempts a pass to A2 (who also has both feet in A's frontcourt). B1 deflects the pass and the ball bounces into A's backcourt. Before anyone else touches the ball, A2 runs into the backcourt (both feet in) and secures the ball. Since team control was not lost would this be a backcourt violation on team A? Or would 9-9-1 apply (i.e., no backcourt violation) since A2 was not "the first to touch a ball aftern it has been in team control in the frontcourt" and "he/she or a teammate" were not "last touched or was touched by the ball in the frontcourt before it went into the backcourt."?
