I think it was to get around a patent in the US originally, but it also works fine for sleeping, and makes folding in the material as you close it a bit easier. Also the beds are in the way of the short side, so you get full standing height in the middle where you need it.
I feel the tent thing on the top is a bit of a waste diagnol. why not have the whole square?
