The slant back looks to borrow from the military Humvee which sometimes sports the slanting cover.I suspect there is immediate separation of the flow due to the hard angle,the downstream re-attachment.
Style-driven,rather than science-driven design.
Although,as the late,great,Bob Parsons would say,"It's way out ahead of nothin'".
