Backcourt Violation? with Video

[letemplay]

Altering the video sitch a hair, what if the player HAD BOTH feet in the frontcourt but had yet to get the ball across and then shovel passed it off his dribble to his teammate still in backcourt? I realize if player picks up his dribble he has front court status and this play would be a violation, but would there need to be clear end of dribble and player control to give ball front court status?
