Cool Isonic Theory ?? Anyone??

Quote from website (Isonic)

"The theory behind the concept: where the water first touches the board, this is where lift is greatest. Where it leaves the board, this is were lift is minimal yet drag is still strong. So effectively, you want more width at the leading edge of the planing surfac and less at the trailing edge of the planing surface. Based on this idea, the concepts of cutaways (Starboard innovation 1999), side cuts (Starboard innovation 2004) and tail wingers (Starboard innovation 2007) were already born. For 2009, Starboard introduces double wingers."

Two points
a) How can edge be less at "trailing edge" than leading .?
Surely any change in width at rear moves trailing edge forward ;ie leading edge at wider point becomes trailing edge ??? (Can you possibly have smaller trailing edge than leading ???)

b) Any cut outs./wingers increase length of trailing edge not reduce it ??? (ie shortest trailing edge would be straight line ???)

Thought idea behind cutouts was to reduce lift but at cost of extra drag ? (ie longer trailing edge but reduced lift to help control at top speeds ??)

Confusing ???
