All TV series and films based on DC Comics coexist in the same multiverse: http://www.buzzfeed.com/jarettwieselman/the-man-at-the-center-of-dcs-tv-multiverse

I think in the universe of 1990 The Flash, there isn't the rule of the same face in two Earths = the same identity in the two Earths.

So, I think it is like that:

- Earth One: Arrow, The Flash, Constantine, Vixen and DC's Legends of Tomorrow - Earth Two: Zoom, Jay Garrick, Jesse Quick... - Earth Three (or another name): 1990 CBS The Flash - Earth Four (or another name): Supergirl
