I think the reasoning behind this is that; he [Savitar] is an entire entity by himself as he is a time remnant of barry that can do other thngs by himself if he wills, and he did too, he travelled through universes, building himself up as a god and a myth, barry didn't do these Savitar did. They aren't quite actually the same person.

As for Eobard, the simplest solution could be that the "remnant" part could be changed to "aberration"
