In my estimation, it is likely the pilot(s) were positioned above the
CG, and would have experienced centrifugal force in the direction
toward the canopy. Perhaps the severed portion of the wing hit the
cabin when it separated and frustrated their egress.

Why do you think the force vector is vertical and not lateral?

I wouldn't expect the force vector to be acting in a vertical (as in
away from the Earth) direction, but in a direction away from the axis
of the roll. If the roll were centered on the aircraft's longitudinal
axis (as a snap roll is) and the pilot were positioned off that axis
toward the canopy, I would expect the force to act toward the canopy
if/when it stabilized.

The twisting moment of the roll might have initially induced some
lateral deflection of the victor, but once (if) it stabilized, there
would no longer be any lateral acceleration resulting from the roll,
only the centrifugal force would remain.

This is difficult to discuss without graphics.

You've never flown aerobatics, have you?
