Diamond flip under flip 800 fps slow motion

Robbyn Spangler-Magby was attempting a hardflip backside 360 over the hip, a trick he refers to as a diamond flip. I'm pretty sure he invented this trick so I guess he can call it whatever he wants. Anyway, as you can see, something went wrong and the board flipped most of the way then flipped back and he miraculously landed on it and rolled away, making the best of a bad situation. Filmed at 800 frames per second with a Redlake N3 high speed camera.
