Unless it has changed very recently, "within the USA" does not include Hawaii...
Hawaii has been fully part of the USA since 1959. I can find no evidence in the rule sheets that flights to/from Hawaii are any different from any other US domestic flight on a xONEn ticket, except in that only one such flight is allowed.
What is your evidence for your assertion?
