The NPCs do have 'memories' of Yggdrasil and should therefore act accordingly.  Having [i]lived[/i] in the world according to whatever backstory and lore the player character gave him.  The NPC then kind of fills in all the gaps left out by the player given lore, meaning there will be quite a few things about NPCs that even their creator wouldn't necessarily know about.

Something I was wondering....
If the events of YGGDRASIL took place almost 600 years ago before Momonga showed up outside E-Rantel (et al), did the NPC's experience the full 600 years? Or did they get the seamless time dilation experience the players did?
