The root cause of this incident was the pilot motoring his seat forward. I hope that one of the lessons learned is that the handling pilot should always be seated correctly such that he can assume full manual control of the aircraft at any time. This captain clearly was not in a position to do that. Did he have his seat back before the co-pilot left the flight deck? Did he motor it back while he was alone on the flight deck? Given the apparent distrust he had of Voyager's autopilot that was a rash move indeed.
Spot on. Endex.
