Pointing your domain to your npub is just a step in specifying your “NIP-05 ID”. The second step is “informing Nostr” about your NIP-05. That is done by adding this info to the kind 0 event (metadata).
So when you add the NIP-05 identifier into your favorite client, it modifies the kind 0 event to inform the rest of users that this is your new “Nostr address”. This is why the same address is displayed on other clients (almost) immediately.
Currently Nostr only allows one of such connections and I don’t think adding more will be possible. Pretty sure this would create confusion and issues.
