I assume you meant push the stick left, lifting the left aileron up, and pushing the left wing down, since it was a left roll.

IF they were still connected is what we're speculating about here, and that's what I'm having trouble with. There is a linkage, otherwise you don't move the stick left or right and have one go up and the other go down.

The more I think about this, the less it makes sense. The video shows virtually no forward airspeed. Ailerons, rudders and elevators are only functional reasonably above stall speed. I don't see any way to do a snap left roll like that without a lot of airspeed even IF he had aileron control on the remaining wing.
