Hadn't seen this before

What bj said. The 2 violations occurred simultaneiously.

Backcourt violation because:
ball was in team control in frontcourt, team A is last to touch the ball before it goes into the backcourt, team A is first to touch the ball after it has been in the backcourt.

The backcourt violation is not for making the ball go into the backcourt, but for being the first to touch it after it has been in the backcourt under the above conditions.

Kicking violation because any "intentional" contact with the ball by the foot/leg is illegal.

Unfortunately, there is some number of officials (and even more coaches) that think that a deflected ball absolves the team with "team control" from a backcourt violation in all cases without regard to who touched it last. (I believe that would actually be true in the NBA).
