Losing all instruments with no visibility is still ejectable even if he thought the engine was still running. He was disorientated and relying on his instruments, when flying under IFR (instrument flight rules) loss of instruments is tantamount to loss of control. The likely outcome in those situations is controlled flight into terrain at 350+mph.

With low altitude being an aggravating factor he was always 100% correct in ejecting and whatever the plane did afterwards is largely irrelevant.

Yes 750m doesn't give much room for errors or time

It was 750 feet, not meters. So much less room.

Even if he held the glide without visibility (harder than it sounds) he would have had less than 60s before eating dirt (rate of descent was ~800ft/min).
