The only thing in common is Boeing made the plane. Literally every other detail is different. One was clearly a mechanical failure in an old, heavily used aircraft and the other is likely a some kind of unexpected automation behavior. Possibilities for Air France include but not limited to: misconfiguration, failure of sensors, programming fault, electronics failure, or pilot not expecting the automation to be in the mode it's in—which could be a training issue, pilot error, or failure of the manufacturer to document the behavior.
