I don't think this is true for FIBA.

A1 inbounds (in the BC?) and throws the ball to A2. A2 is standing in the FC; he then jumps
catchs the ball
and lands in the BC?
I don't see why this wouldn't be a BC violation.
They have team control
Team A was the last to touch it in the FC
and the first to touch it in the BC

I suppose it's no a BC-vio under rules-sets wich say "no team control" during throw-ins though.
