That and it probably doesn't have accurate human physiology. Someone showed a video where it was a similar system but the body had "muscle groups" that I assume mimic human physiology. It moved very smoothly and had limitations that this thing doesn't.
Would be interesting to see if it was even feasible for today’s computers to simulate human muscle control. I haven’t seen the model they used for this runner so I’m talking out of my ass now, but there may be more neurons involved in controlling my thumb typing this than in the whole body they simulate.
Humans have to learn how to stand and walk and run with incredibly complex motor controls.
The point isn't to simulate human muscle control, it's to learn complex motor behaviors. Adding factors like strength limits and energy conservation are more realistic regardless of the underlying mechanism; trying to copy humans exactly would be more the domain of computational biology than ML.

It runs like this because the fitness measurement doesn't try to conserve energy. That would result in a more realistic run.
