The rear windshield is a complimentary angle to the roofline, making a smooth entrance to flow, and the "front" (thinking in correct orientation) appears to drop off, in such a manner that appears like the illustration on the webpage.
That's the only thing I can think of... maybe they're inside-joking about the pressure thrust capability?
