It's a design that can reduce pressure injuries compared to a rigid exoskeleton, since it seems to operate with straps attached to powered reels instead of metal. Those anchor points, however, still will very likely cause pressure injuries if worn too long. I also don't think I would call something using fabric straps an "exoskeleton."
Also, the man's gait who's using the suit is still FAR from something I'd call steady. He'd still need a walker.
