This is a practice of Bushiroad called "future-proofing" meaning they make accomodations for future card mechanics with present-day cards. Think of Vanguard where cards had the text "blah blah a Grade 3 or higher card" years before the first official, tournament-legal Grade 4 ridable unit was released (not the Great Nature one; but even that was at least a year in the making).

No guarantees, but at least the possibility is open.
