I do have a "cluster" in which I share policy across multiple devices, but we don't use a VIP. (I do the poor man's load balancing by way of proxy PAC logic.).
When I connect to the "wrong" box I get a message "Another tomcat is already attached to this cluster. Please log on to that one. " and a link to it, where I suppose cluster master will answer. I'm on 18.104.22.168
I'm not sure that answers any question you asked, but I figured there may be some value in describing behavior in another working setup.
