Andrew,
The left-hand-side panel on the Add Database dialog contains detail on the source control database that you are currently connected to, rather than the server from which you are adding databases. The server name from which you are adding databases is listed just above the database list.
I can see where the confusion arises so I'll see if we can modify this dialog to better reflect the server you're adding databases from.
