To me, this seems entirely plausible, even if the movement is relatively slow. Do pilots have their lunch tray on their lap (between the stomach and the controls) when they eat? Maybe the pilot asked the flight attendant to move the seat back so that they could eat comfortably (as they obviously cannot reach that control themselves), and it was moved in the wrong direction accidentally?
