Yeah, some mobs do follow you. While it's sometimes adorable, Ravlow is right in that it mainly prevents you from using AOEs. Maybe the monster wikis/databases are going to have to update it to Non-Aggressive, Aggressive, and Follows?
So far I've seen these mob types follow:
It makes it really scary when you are running past high level mobs,and you can't afford to look back to see if that dot on the minimap is a wolf about to eat you or just a friendly coblyn. >.<
Though, I've never seen them follow very far, so maybe you bugged that one out if you got it all the way to another camp.
