This is a braced roll. The backspot grabbed the outside hand of the top, so there was contact with someone on the ground. To distinguish a braced roll from a flip remember the definition of the roll.
Roll: A hip-over-head rotation that is executed either on the performing surface or in a partner stunt in which the top person is in contact with a person on the ground.
Braced Flip: A pyramid in which a braced top person performs a hip-over-head rotation while being released from all persons on the performing surface. The bracers are in stunts.
