I see what you're driving at now and as a mechanical explanation of the exact process it certainly has merits. However, I suspect that the reaction of the PF would have manifested itself in a similar manner no matter what the input mode. This was not a pilot who was thinking clearly or logically and this was not a crew that was following any known procedure. The proper management of the flight deck was missing and whilst I like the mechanical process you lay out I don't see it as having anything to do with the development of the accident other than the in the most peripheral way.
A330 pilots who have commented on the flight characteristics of the aircraft on these threads indicate that the aircraft is a very stable machine which quickly recovers a stable flight regime even in ALT2. The aircraft seems to be designed to help the pilot as long as the pilot trusts the aircraft.
