He didn’t lose the controls _or_ the instruments. He lost his HUD and the primary flight display. But the standby instrument display was still working correctly, and the fly–by–wire system was still accepting input and acting on it correctly. Sure, if those things had failed then ejecting would have been fine. But he didn’t even check them to see if they were still working or not, he just bailed out of a flyable plane.
