Centre stands....for better or worse.

Looks to me like it was a half hearted weak attempt to pull the bike up when it wasn't levelled first, when the bike drops down it's more on the left side of the stand, so as it goes down the momentum pulls the bike away from him.
Silly, but shit happens.  :\

Yep I would go with that. I always make sure that both stand feet are flat square on the floor before pushing down with foot and lifting up from the back of the bike at the same time

I don't think its placed in the perfect sweet spot I think it could be easier to put on but i suppose its in the only place it could go
