No.  IMO it's a bug in the interaction between emacs and the window manager.

With my version of emacs "22.0.50.1", and with my window manager
(WindowMaker), it works as you want.

You could use:

(defvar fpx-compensation 0)
(defvar fpy-compensation -1)

  (setq fpx (cdr (assoc 'left (frame-parameters))))
  (setq fpy (cdr (assoc 'top  (frame-parameters))))
  (setq fpx (+ 1 fpx fpx-compensation))
  (setq fpy (+ 1 fpy fpy-compensation))
  (set-frame-position (next-frame) fpx fpy)
