From the report, the ejection was initiated only 3.7 seconds after lift-off, by which time the aircraft had already past 60 degrees of bank and had started descending. The canopy jettison activated 0.3 seconds later at 69 degrees of bank. The height is not specifically mentioned, but it wouldn't have been much given the impact was only 4 seconds after ejection initiation.
Allowing for human reaction time, the only option for survival would have been recognition that rudder input was required to correct the situation, or unloading the aircraft with max left roll. The board makes clear why neither of these options would have seemed obvious at the time.
