From what I think, using Eyes Of Heaven as an example, the "universes" exist simultaneously. The original never ended...or at least the one we were shown wasn't the "correct" one in a sense. If the original did end, then the Eyes Of Heaven didn't happen at all (Sorry if I may be using a non-canon source, but it's the best way I can explain it. So to sum it up, there are multiple universes. The Original, the Ireneverse, The SBRVerse, and the corrected timeline.
