Wayne Lynch footage

Looking at fascinating footage of Wayne Lynch. Presumably surfing the Double Ender?
The ease with which he turns the board completely on rail is fascinating.
More impressively -- it seems to me the board allows the back foot to be placed much further forward when turning, in front of the fin.
See ~2:10 and images:
Anyone surfed one or has experience with one that can comment on this design?
(By the way, I found the term "double ender" confusing. It's supposed to say the nose and tail, arbitrarily determined at 1' from either tip, look the same. But it's a wide point back design. The term for some reason makes me think it's supposed to be symmetric tip to tip.)
