Misunderstood the functionality of this feature. I was under the impression if i was onsite and tried to connect it would not allow or auto-disconnect me, but TAC clarified that the purpose of the setting is to disconnect you if you initiate an AnyConnect session in an untrusted network and move to a trusted. Ex - put your laptop to sleep while on AnyConnect at home and connect to your enterprise wifi with AnyConnect still running when your laptop wakes up
