I think this is legal.

What could possibly be illegal about it? A2 has backcourt status the entire time. A2 starts with backcourt status as he is standing with one foot on each side of the line. A2 catches the ball without moving and thus still has backcourt status. A2 picks up his frontcourt foot and continues to maintain his backcourt status as his other foot is still touching the backcourt.

What are going to penalize him for ... a back and back vilolation?
