Just ran across this...
He would've been fine if he would have just put the 'chute out and stayed off the brake. I've watched it several times, there's over two full seconds from the car getting out of shape to when it spit the diff. That's what ripped the rear end out, he grabbed the brake which sent the rear of the car up in the air. With the rear wheels locked, it ripped the rod ends off the ladder bar when it landed.
Still, you hate to see it happen, glad he walked away. I doubt the car's really banged up too bad. He's lucky.
