Weird Bug with Escape Causing No Loss of Aggro

I've noticed in the past few days that everytime I escape in an instanced zone where the NPC's are somewhat close to the zone in, they're following me back. They aren't bringing other aggro either. It might be a possibility that if you have a debuff or DoT on a mob and hit escape, you can solo pull anything somewhat close to the zoneline straight to a group at the zoneline if you send a scout out to nab it.

EDIT: This is just a bug in Nektropos. Not sure if it works in other zones, but I do know you can single mobs to the zone in there. I pulled Billy in the Chapel straight to the zone in solo.

EDIT #2: It's working for me in RoV now if you're somewhat close to the zoneline. I was singling the Guard Captain to the zoneline last night.
