To me it seems silly and unnecessarily dangerous. I imagine there are some positives like being lightweight, cheap, the rungs are probably good for crampons.
But why tie two together in the middle? Just get a long one. And if your life depends on it why not make it a bit wider and have better anchors on either side. Some light railings. Design it to be super portable, rich people would pay for it.
Really the thing that gets me is they tie two together in the dead center.
