I think you are mistaken in what you think it does. I am pretty sure what
it does is allow you to call named src-blocks with this syntax:

#+call: some-func-in-lob(args)

It doesn't make the functions in the code blocks necessarily available in
another code block (although through side effects for  emacs-lisp, that
might happen).

I think what you want (this works for emacs-lisp)

is a file, say f1.org containing

#+BEGIN_SRC emacs-lisp :tangle f1.el
(defun mfe () 8)
#+END_SRC


Then, in another file you can do:
#+BEGIN_SRC emacs-lisp
(org-babel-load-file "f1.org")
(mfe)
#+END_SRC

and you will get 8. org-babel-load

This isn't possible in other languages. You can of course have an elisp
block to tangle f1.org, and then if it was python, for example, you could
import the functions in a python block.
