I think that's more of a philosophical question than anything else.

That's like asking if another version of you in an identical world would make the same decision at the same point every time, but then you would need to expand that to every single living being and every single possible natural occurrence across their entire history because any time the tiniest thing possible changes, then that will have an exponential effect on the changes and different paths take on other shards.


The lore does state that there is a difference between the Shards, and even absent of Ascian intervention, they could have progressed differently:

I would think the inequality of Light and Dark could subtly steer each Shard in different ways, to the point where after 12,000 years (not including time differences), they will be in completely different places due to different things happening on each Shard due to the balance of aether on each one, and those different events causing even more different events that wouldn't have happened on the other Shards, so on and so on which each different event having a knock-on effect. And then the time differences between worlds would also probably have an effect as well.
