IMAP allows folders present on the server which are not presented to the client when it logs in, hence the idea of subscribing. Unsubscribed folders are great for archiving old stuff that you don't really need to see but need to keep around. By not subscribing after you renamed the folder to include a dot it remained invisible to your client.
This is actually client-specific, some clients don't support subscriptions at all and others can be configured to use or not use them.
I've written a bit more about how I think they should be implemented in http://www.imapwiki.org/ClientImplementation/MailboxList -> Subscriptions.
