They're also interacting with the environment (vaulting boxes / walls), which implies they either know their 3D position very accurately, or they have some form of sensors and can adapt a bit.
My point is that if you interrupt the sequence by pushing it over or standing in front of it, the unit will not be able to recover or mitigate the issue. I’m not sure about the models in the video but they should enter a safe state, hopefully gracefully.
