My mistake was reading the preamble, before looking at the actual diagrams. It was confusing me that he was mentioning a ton of old, tried and true designs.
I think what his design is doing is addressing the need for a sharp, flat, fast lens. "...virtually all high-speed photographic lenses designed to date are compromised by the need to balance large aberrations against each other. Most often these designs are notably soft in the outer sub-group of the image field, and must be stopped far down to achieve good performance. "
