And here is mine, which is very similar. The big difference is that
once you jumped back to the saved position, you can jump between the
two by using jump-last-posiiton:

(defun save-current-position ()
  "Saves current cursor position in register 0"
  (interactive)
  (point-to-register 0)
  (delete (assoc 1 register-alist) register-alist)
  (message "Position saved."))

(defun jump-last-position ()
  "Jump to position saved with previous `save-current-position´,
OR if run two times with no `save-current-position´ in between,
jump to the last position it was run from."
  (interactive)
  (if (get-register 0)
      (progn
        (point-to-register 1)
        (jump-to-register 0)
        (delete (assoc 0 register-alist) register-alist)
        (message "Jumped to last saved or last jump-position"))
    (if (get-register 1)
        (progn
          (point-to-register 0)
          (jump-to-register 1)
          (delete (assoc 1 register-alist) register-alist)
          (message "Jumped to last saved or last jump-position"))
      (message "No pos saved"))))

Of course it is quite ugly to just hijack register 0, but it is a
register that a user at least cannot type using the keyboard (or maybe
by using C-q first, I don't know and I don't care... :)
