Harley Davidson Dyna Fat Bob ": Why is FXDF FLDF place?

FX describes Harleys to sport (thin) front tires and FL describes the fat one with the front wheel (Fat Boys & Cruises / Baggers). The Dyna Fat Bob Harley is the ONLY fat tire on the front and a name FX. This is really listening to me and the dealer can not even answer this for me.

So … in 100 years, what difference will it make? Does world will end just because some stupid motorcycle design does not follow the same letter designation as the rest?
