I have not seen one of those in person, but based on the pic, the new nut's inner diameter clears the flare end of the pipe, and the washer, which is expandable (it is open ended and wound - not a typical solid/closed circle), also clears the flare when expanded and is the surface that the nut uses to apply pressure to the flat portion of the flare end.
