Not really, on the same 2nd level headline calling it with M-x and M-:
give different messages, and only in the first case a useful one. 

With point at start of ** 2nd level

#+begin_src org
* 1st level
Hello 
** 2nd level
Work
#+end_src

,-----------------------------------------------------
| Eval: (org-display-outline-path)
| Eval: (call-interactively 'org-display-outline-path)
`-----------------------------------------------------

both print this in the message buffer

,--------------------------------------
| byte-code: End of buffer
| #("1st level" 0 9 (face org-level-1))
`--------------------------------------

while using M-x shows the string "1st Level" as expected.
