The key thing is, there was only one timeline until the events of Shadowbringers caused it to diverge into one path that leads to the Eighth Calamity and a second path that does not. The second path could not have formed if G'raha did not come back from the future of the first path, but now they are simply equal paths for history to take.

I feel like it's something that is actually quite simple but in a way that is hard to explain, especially if people have a fundamentally different concept of how time works.
Oh well, I was under the impression that there was frustration that FFXIV has two different types of time travel existing within the same narrative.
Also Exarch!G’raha’s original timeline doesn’t just diverge from the new one (our main timeline) in regards to the future. Because of Endwalker, Exarch!G’raha’s timeline also has to have a slightly different past as well since it never had its WoL travel back in time to do a causal loop, because the WoL was dead (and the 8th Umbral Calamity occurred instead of the second Final Days occurring), so therefore the Hydaelyn of that timeline still sundered the original world even without having met the WoL in Elpis.
