The defender may not break the imaginary plane during a throwin until the ball has been released on a throw-in pass. If the defender breaks the imaginary plane during a throwin before the ball has been released on a throw-in pass, the defender’s team will receive a team warning, or if the team has already been warned for one of the four delay situations, this action would result in a team technical foul. If the defender contacts the ball after breaking the imaginary plane, it is a player technical foul and a team warning will be recorded.

By setting the ball on the floor, A1 has, indeed, released the ball, however, I don't believe that there has been a throwin pass.

Has A1 done anything wrong?
