Should he have just coasted all the way down the hill? How fast would he be going by then? He seemed to do a pretty good job of braking as much as possible while still being able to steer enough.
Him going sideways meant his braking wasn't working. If there's slipping you want to let off the brake and down shift (you can do this in automatics) to the lowest gear that doesn't make you slip. Staying straight to where your wheels aren't slipping is a priority over braking or getting slower. The only way of slowing is to have traction, and you don't want it while sideways.
I would have tried keeping straight and then veered over into the dry lane and started slowing down.

Put it in a low gear. The engine will slow the vehicle and prevent you from gaining too much momentum while still allowing you to control it.
He didn’t do a terrible job though, especially if there were cars ahead of him.
