Default Responders with multiple Responder Ports in a single Device.

I have a question about Responders with multiple Responder Ports in a single Device.

If I have a single device with 4 responder ports, each responder port needs his own UID. So the device has 4 UIDs ?
In case a single controller is connected to all 4 responder ports, it will find “4 devices”. But based on the binding UID it knows which is the primary port, and will communicate only though this port?

Controller X -> Resp. Port A UIDa (Binding UIDa)
Controller X -> Resp. Port B UIDb (Binding UIDa)
Controller X -> Resp. Port C UIDc (Binding UIDa)
Controller X -> Resp. Port D UIDd (Binding UIDa)

What happened when the single device with 4 responder is connected to 2 Controllers?

Controller X -> Resp. Port A UIDa (Binding UIDa)
Controller X -> Resp. Port B UIDb (Binding UIDa)

Controller Y -> Resp. Port C UIDc (Binding UIDa)
Controller Y -> Resp. Port D UIDd (Binding UIDa)

In that example both controllers knows the primary port, but only controller x has access to it?

The controller Y knows that UIDc and UIDd have the same Binding UID so it knows that is one single device with multiple ports and communicate to one of the accessible UIDs (UIDc or UIDd) ?

Or do I completely misunderstand the idea behind multiple responder ports and binding UID?


Thanks

Robert
