Yes, this is certainly a very bad idea.  goto-char is used many times in lisp programs, also in Org, so executing normal Org functions will be slowed down and reveal parts that should not be revealed.

Instead you should be advising session-jump-to-last-change itself.
If you do not want to expand a full entry if the change was in 
a headline, you can check for invisibility:

(defadvice session-jump-to-last-change (after org-expand activate compile)
  "Reveal hidden point after jumping."
  (when (and (eq major-mode 'org-mode)
