They probably just made an Ash/Anabel ship for the hell of it. There probably is no deeper meaning, and it's kind of strange since it wasn't made to push another ship either.
In any case, I'm glad the writers are willing to put Ash in new ships without Misty around. The closer we get to the canon death of Pokeshipping, the better.
