As to lifting up the load, you'd be doing a deadlift from the ground—not too good for the back. And once the load was lifted to the correct height, the handles would be quite high, making for a higher center of gravity and increasing the chances of toppling; the gentleman's hands seem to be grabbing the handles just below his chest level when a level just below the waist would offer far more stability. Looks extremely awkward to me.
I noticed that hand position too, and with the grips straight back it would be pretty awful at that height. I also think the handle height needs to be low.
I wonder if this isn't one of those cult-like things, where people get all glassy eyed and overexcited about the uniqueness of the thing and fail to notice that it's pretty much a total design failure.
Cyclists don't get into cults about bicycle stuff, do they?
