What do you make of this ?

The more regular python is designed to stabilise dead ahead purely by having weight on it which it does not have as he leans them here hence it flops. The other one is not going to get more stable via weight but may or may not be more stable anyway. No way to tell unless he's explaining it in his video. Why is there a spanner attached to the chassis? Is it a tensioner for the rear rubber band suspension? The brake cable is not well mounted in the lever suggesting he has fallen off it on that side. The derailleur looks very close to the ground. It could be the camera angle but it looks like he uses a large front ring but also a large freewheel / cassette!? Can't think why you'd go large on both ends of the chain. He's not worried by scuffing his pedals.

I suppose the left one has a head tube angle akin to a normal bike ? so shows normal bike behavior ?

One of his bikes [ maybe this one ] has a video showing him using the ratchet to alter the pivot angle by pulling the rear wheel towards the pivot , which may be why the pedals end up close to the floor.

he seems to have built several bicycles however it is hard to ascertain his ultimate goal ?
