Don't be so literal man, I was saying that like an analogy. At the core he's Future Flash, but he pretends to be Savitar on the surface.

Future Flash also sealed Barry into a rupture, trapping him in the Speed Force. In the show he does it with Wally instead, but it is still close enough to be a comics mythology nod.
