First of all, we don't actually know that the original timeline is in any way relevant to MK11 (other than Kronika possibly preferring it).
But more importantly, it's not just that the first timeline "didn't happen," it's more like those games are so ancient, and everything about them has been retconned so heavily, that even if they did happen, they certainly did not happen the way MK1/2/3/4/etc portrayed it back in the day.
So IMO relying on them as evidence of anything at this point is pretty shaky.
