I have followed Boston Dynamics for years.
They still use the ubiquitous "permanently bent knee" method of assisting keeping the mass centre over the ankle, whereas humans can do a continuous re-balance with other posture moves. Clearly they have mastered the temporary moves through unstable (unsupported) states by body inertia, and just-in-time arrival of a well placed foot. It's awesome!
I suspect the automaton sequence was captured in part from an instrumented exoskeleton strapped to a dancing human. I am unsure if there are yet robots that can wander around of their own volition, but I suppose a bit of Tesla-style Elon Musk software, a GPS, give it a destination, and you could have it strolling off to the next charge point in a Walmart car park, and return with your shopping. Maybe they should also have to wear a mask, even if they don't need it, and set an example.
