The guy should pivot in place, bend at the knees, grab the handles, stand, and then pivot in place. It’s like people decided to invent a power suit because they forgot how to use their feet.
The point is that this is a realistic movement people can find themselves doing and this is research into making that better/safer.
In complete isolation, this might be completely replaced by different lifting technique.
But what about in cramped quarters where turning isn't easy, or with an awkward object?
What about in combination with other devices which make the body strong along another axis?
As far as bending at the knees though, you should read Why You SHOULD Use Your Back as a Crane[1].
