Clarification on Backcourt Violation

[Adam]

so- to generalize- once the offensive team establishes control in the frontcourt, any subsequent determination of a backcourt violation is based on which team touched it last in the front court prior to the ball returning to the backcourt.

Would this be true regardless of how many times the defense touched it or if they established control?

Example- A1 establishes control in the frontcourt. B1 steals the ball establishes control and remains on the same end of the court. A1 knocks the ball away from B1 into the opposite end (backcourt for team A) and retrieves it.

Is this a backcourt violation on A1?

If B1 establishes control, then A is now on defense. The number of times it is touched isn't relevant, but team control is.
