The only part of the defender that touches the shooter is his left arm, which makes contact with the shooter's arm and the ball. The fall looked nasty, but it wasn't because of any excessive contact.

You cannot see all the contact from the angle this was taken. The original video you posted from the same angle as the C's viewpoint indicates contact to the head. And it was the C who made the "crossed arms" signal.
