At 0:55 through 1:05, there is no rudder input that I could see. This goes back to the moose stall, aileron input on a drop wing, accelerates the drop of the wing, downward motion of the aileron generates drag on the down wing and upward motion of the upward wing release draw wile generating a low energy vortex at the tip, increasing lift at the wing tip...
Did flight training on an acrobatic airplane, and even knowing that I had to input rudder, it took me about 5 tries to remove the instinctive visual input of aileron... the gnomonic I use to remember this is, when near the ground, use your feet. On most days doing traffics, I still practice on approach to correct with rudder only.
Now, could he have saved it, it's hard to know at these speeds and altitudes; but it's always a loosing bet to introduce aileron control.
It's hard to see this happen... I'm very sorry for this event.
