The examination requirement is that aileron should not be used to lift/arrest a dropped wing during a stall. It is acceptable to use rudder to arrest a dropping wing but not to lift it. The whole rationale is that the prime action should be reduction of AOA; remember we're trying to teach an automatic response to an unplanned manoeuvre in a wide variety of aircraft types. Indeed, in theory the same technique could be used on anything from a Cessna to a Boeing.
