Him and the other snakes I picked up are all in tubs on my office desk with heat tape as a quarantine area. My other snakes are downstairs while these ones are upstairs.

They are all in tubs with blocked out sides so they can't see each other, with two hides and a water dish. That room is dark except for daylight coming through the closed blinds and the light when I come into the room, although I usually turn it on very dimly as to not startle the snakes.

That time his "movement" only lasted a short time, it usually lasts for longer, and consists of more twisting of the entire top section of his body, not just the neck. And not only that, he doesn't often right himself and slither away like he does in that video, he will stop with his head upside down for a short period then corkscrew again and often flop forward unintentionally and then stay still.

Im also concerned about the fact that I found him with his belly facing outwards and not to the ground
