Yeah, but that doesn't tell me that they named themselves "North/South/East/West" only for World 2.0. The fact that there were four groups already, and that they refer to the dead ones as "West" suggests that the division into the four cardinal directions was established in World 1.0. Yes, maybe in 1.0 they didn't formally divide the world into four sections (because we know they didn't do anything formally, thus the Snarl) but it feels like they at least informally grouped themselves by cardinal direction.
