I suspect that works fine if the forks are tied together properly.

I've ridden a few bikes where the forks twist under braking with a single disc.

Under extreme conditions I suppose there could be some independant movement of the forks, we've all seen that picture of one snapping.

Don't ask me

That's what he does and apparently it works.

I can't do rolling stoppies and have no intention of learning them so can't test it myself.

Stunters don't work to conventional physics, they are in league with the Devil and use black arts!
