That's because your JIDs only differ by 1 bit, the default nickname is the same
as the "user" part of the JID (e.g. uwog22), and the unique names used in the
tube are a modified base64 encoding of the nickname to guarantee
collision-avoidance (unless the nickname is far too long, in which case a hash
is used and collisions are merely very unlikely).
