A regular airplane in normal flight is aerodynamically stable in roll, meaning any roll rate will generate a moment about the longitudinal axis to counter the roll. Once the wing stalls, this changes and roll stability is lost. When in a stall, if the wing rolls for any reason, the aerodynamic moments will tend to increase the roll rather than stop it. This characteristic is what makes spins and snap rolls possible.

Once a full stall is entered, the wings won't stay level for long unless you apply corrections to keep them level. Geist mentioned the nose drops on his Extra; that ends the stall and puts you back in regular flight.

Godfrey, I agree with everything you said.
