WillDAQ....just to answer your question....
It is a possible theory, however the point of modern zero zero seats is that he should have had time to point the aircraft but still eject 'at the last moment'.
Modern ejection seats are way better than they used to be, but they still have their limitations. The zero zero is based on zero altitude and zero forward airspeed....but what still needs to be considered in the seat's "operating envelope" is the 3rd "zero" which is rate of descent or sink rate.
Just to paint an extreme, imagine being out of control & descending at 20,000 feet per minute, you'd need to eject well above the ground to allow the chute to open fully and give you a few swings before touching down......ie: if you pulled the handle just a few feet before the ground, it simply won't work.
That being said, the rate of descent in the posted video of the accident appears to be far from excessive.....which would allow a lowish ejection.
IMHO, I don't agree with the idea he intentionally rode it in to avoid built up areas.....if that was the case, you'd do your best, then at some point give it away....it all looked very benign.
best wishes to his family.
.......but, over to the investigators.
