I think it is IMPOSSIBLE for the CG to stay on a
straight line during a snap roll. Think about it, even
a fully stalled wing generates lift, and has a vector.
For a snap to NOT cause the CG to wander would require
each wing panel to have equal lift, in opposite
directions. Sorry, that is not going to happen.

Ever hear an aerobatic pilot talk about being
weightless during a snap roll? Yeah, right.

The rulebook must be wrong. Just my opinion.
