I think that Flashpoint changed every New Earth character into a Prime Earth character, regardless of similarities and shared origins. I think the Rebirth issue started with New Earth Wally floating through the Speed Force, looking down on the Prime Earth.

As he got closer, his memories changed to match the Prime Earth, suddenly realizing that he always had a black cousin also named Wally. When New Earth Wally finally contacted Prime Earth Barry, Barry remembered the pre-Flashpoint world for just a second. Then when he pulled New Earth Wally out of the Speed Force, he then became Prime Earth Wally. And both Wally and Barry received new Prime Earth memories.

I think that would be the easiest way to look at this post-Rebirth world. For the most part, the New 52 continuity continues, with only a few adjustments.
