I have troube understanding what you mean.

An outline heading looks like this

*** heading

If the cursor is at the first character of that line, org-outline- 
level will return
3.  If the line looks different, the return value will be badly  
determined (governed by the most recent match of a regular expression  
anywhere in Emacs, might be anything).

If you need to find out, in a lisp program, if you are at the  
beginning of a headline, use

  (and (org-at-heading-p t) (bolp))
