It's describing how flare may occur in a lens with this construction.

Thanks... And I suppose there's another drawing, which describes that this monster will be equipped with nano crystal coating <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='

The coatings to reduce ghosting are an integral part of this patent application, as much as the lens groupings. One of the main points is that both sides of the lens receives a multilayer AR coating. Another part of the patent describes the formula of the multilayer AR coating.
The patents references an earlier (2009) super-wide lens design from a Taiwan optical company, which it seems to improve upon.
