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.

The crevasses change shape and snow quantities, so there is no perfect route. Aluminum is light and doesn’t lose strength in the cold. Climbing rope is engineered and has a strength rating, making it a convenient marriage. Though I’d be surprised if they didn’t have some sort of aluminum bracket to go with the ladders.
