JMO that would be No, not exclusionary but possible. Many athletes injure their knees and end up with hyperextended knees. Dancers, gymnasts, skiers, football QBs ... and some people just have a lot of flexibility, children & teens?
In earlier threads, some poster(s) thought they saw the stance and steps specifically of a ballet dancer? Several useful photos of real legs with and without hyperextended knees:

I noticed something else. At the end of the video, from about 2:00 but right at 2:05 - that is perhaps the best view of how slim SwatPerp really is with a thin profile in the gut, hips and legs. Also there is a very clear view of the topside of the shoes or boots. IMO I can see laces.
Remember how it sometimes looks like shoe covers or flippers when the toe of the SP's shoe meets the shadow on the floor? In this downward camera view it can be seen there are no extending covers on the shoes. The images from 2:00 are on that other back hall solid color flooring. I remember lots of discussion of what was in his free hand, what room numbers, but I don't remember looking just at the very bottom right corner of the frame at just those shoes/boots. If 2:05 were an image of some sneakers, the company name or logo might be there on the side, but could be covered by black tape.
