2 points or 3?

[C_Money]

We've got a guy in our noon pickup game that has a strange shooting technique. He picks up his right foot with the ball overhead (picture Ralph Macchio doing the Crane in Karate Kid), and hoists away. One day he did this while straddling the 3-point line, right foot inside, left foot behind. He insists that it was a 3-pointer, since his only contact with the court was behind the arc. Others say that his shooting motion begins with the lifting of the foot. Any thoughts?
