I’m not sure which video you’re looking at, but the aircraft clearly goes through a 1 turn spin just before the ejection. The very start of the spin can’t be seen because the camera briefly moves off target at just about that point. Once the aircraft comes back into view it has spun 180 degrees and the belly is facing the camera. You can see it continue through the final 180 degrees of the spin followed by a brief recovery then ejection. This is not “rolling level” because the aircraft nose is pointed straight at the ground. Ejecting from this low of an altitude in a nose down vertical descent would be a challenge for any ejection seat.
