It's because of this:

(defun erc-autojoin-channels (server nick)
  "Autojoin channels in `erc-autojoin-channels-alist'."

[...]

    ;; `erc-autojoin-timing' is `connect':
    (dolist (l erc-autojoin-channels-alist)
      (when (string-match (car l) server)
	(dolist (chan (cdr l))
	  (erc-server-join-channel server chan)))))
  ;; Return nil to avoid stomping on any other hook funcs.
  nil)

This code is meant to autojoin all channels you've previously been in,
but it doesn't check if you're already there using a different ident...

I'm quite unfamiliar with the erc code base, so I'm not quite sure what
the right fix here is.
