I suspect that the argument of the people who support the split following the latest episode of Arrow is that Mia William and Zoe are all very different now from their Earth-1 counterparts so this was a reboot, thus a split is required. That in theory debunks the argument that they are the same characters.

Well no. That argument actually means: Both original and new multiverse versions of characters are pretty much the same before they experienced Crisis (the events that happened before the Crisis began occured in pretty much the same way in both multiverses), so there is no need for seprate pages just to cover events after Crisis. We know that for example what happened to John after Crisis on Earth-1 is compeletly different from what happened to him after Crisis on Earth-Prime (because... he died).

That point doesn't change from the episode. 90% of Mia's history is after Crisis so of course it would be a lot different in Earth-1 and Prime.
