Jaune's sword is double edged while the Warrior King's is single edged for one, and they have used double edged swords in WoR before so it's not just stylistic limitations that make it a different sword (not to mention the completely different handle as well).

And no WoR has said anything about Jaune or the Warrior King's sword.
