Also, pony tail dude kinda kept some of his dignity because at least he can feel good about "standing up for himself" against a guy who is much bigger and stronger than him. Don't underestimate the importance of that in this day and age when everybody has a gun.
If he was completely humiliated, he would've been pressed to retaliate somehow. Especially given the fact that the beat down was recorded and went viral. Now he can lick his wounds and move on with his life without feeling like he gotta do something drastic to save face.
