The geometric pattern described depends on many things and is not per definition a circle, but could equally be an ellipsoid, a triangle, Bernoulli's lemniscate or a clothoid loop.
As to the general idea of constructing neologisms in Japanese by people who neither speak Japanese nor master Japanese linguistics I would have hoped that the sense of that is sort of self-explanatory, although perhaps in the UK you could find some to back up the opposite view, although it is not clear to me exactly what they would be backing up with the opposite view.
Drawing in the concept of ensō to me resembles pseudo-mysthicism that is better left in the ninjer domain. All we have hear really are the biomechanics of pressure applied in renraku-waza.
I was hoping there was such a term somewhere to explain this type of drill. I guess I'm out of luck then
In the UK they have such crazy names for waza, it makes my eyes bleed from time to time reading them, I see your point there. What about the word; Rūpu, Wa (輪) or Mugen Rūpu (無限ループ). Can any of these be put together into something descriptive of a pattern of an exercise that goes in a loop? You kind of end up at the place you started, with renraku-waza of osaekomi in-between.
EDIT: The video is not just a demonstration of random osaekomi-waza, it is a drill where you practice several osaekomi-waza with an uke trying to escape in a pre-defined pattern, and you end up where you started and can continue until you get really, really hungry or thirsty. It is very good for kids to learn this way, like the osaekomi part of katame-no-kata
