The only reason I can think of is if you're trying to make the chassis fit within the 112 inch frame perimeter.
Otherwise, I don't see a structural benefit to cutting the corners off.

If I had to guess it would be that they're trying to keep all the 1x1s the same length for convenience? Then cut ends to keep it flush. Personally though if that's it then I might rather have the extra support from corners.
