I don't think it says exactly that. It says he still had backup instruments and good flight controls and ejected from a flyable plane. If that were strictly true, they'd be well within standards to fire him.
I'm not sure I agree though -- it was a shitty situation all around, missed approach, go around, instrument only conditions, lightning strike that took out the HMD and most of the cockpit displays. That's a real shitshow in a completely fly by wire plane.
