Doesn't make much sense to me. Apart from the fact that a humanoid could walk to the workplace – which it probably can't. For the actual task it would be much easier to use a non-humanoid with a carriage and several axes.

Also it is a bit of a hoax because the whole humanoid reporting kind of suggests the robot is autonomous while one the image you can see a camera mounted on top of the wall and there's probably some huge computer in the back.

EDIT: Here's some actual information about the project: https://www.aist.go.jp/aist_j/press_release/pr2018/pr2018092...
