On this deflected throw-in, is B1 still considered a defender or not?

How can there be a "defender" when neither team had established themselves as the offensive team?

When airborne A2 grabbed the deflected throw-in, that's when team A established player and team control, and that's also when team A became the offensive team and team B became the defensive team. Iow, deciding when or if B1 becomes a defender doesn't enter at all into the final call; it's simply not relevant when B1 becomes a defender. The only pertinent fact needed is that after gaining control, A2 did not meet the requirements of the exception listed in 9-9-3 and committed a violation.
