In my opinion the guy didn't want to drift around that bend.
He just starts to brake too late, the car oversteers and he doesn't know very well how to deal with it. He didn't undo the opposite-lock (or accelerate) and ended up against the wall.
I feel a bit sorry for him.
Fortunately, it looks like there was no big damage and no one got hurt.
