I'm not surprised. He said he was a fan of the KOTOR games and even admitted that Kylo Ren was based on Revan to the point of calling him the "Scourge of Malachor" which never made much sense since Rebels shows that the place is uninhabited and the comics or whatever just show him going down there to get a lightsaber. What exactly is he the scourge of? Nothing. JJ just wanted his own Revan and the title sounded neat I guess without putting much thought into it other than Revan parallels.
