There's a practical aspect to it, which I assume was intentional given the engineering challenge of being able to fully rotate torso like that, etc.

Most of these humanoid robots (e.g. TeslaBot in it's current state) walk slowly, which limits productivity. It wouldn't matter if the job was standing at an assembly station, but anything with legs is obviously targetting more general use cases such as "gofer" - fetching parts from bins, etc.

The benefit of electro-Atlas (they should have a naming competition!) is that it can essentially move or look in any direction, which means it has to walk/turn much less to get into a preferred orientation or move to a target location. It's a bit like the early "micromouse" competition entrants where they went from the initial car-like designs to omnidirectional ones (using omnidirectional wheels) so that they could change direction without needing to turn - just scoot off at 90 degrees to previous direction.
