Did he really only do that one pull-up or has the video been cut?

Because seriously, I could do a couple of clean pull-ups at over 130 kilos (I've weighed in at 1200 quarter pounders at some points in my life). At 100 KG I could easily do like 20 clean pull-ups. That be 220 freedom units. No legs flailing, no starting with my legs on the ground, etc. I do not consider myself the prime example of fitness, I'm a fat fuck with, luckily, a lot of muscle mass hiding under said fat.
