Yes, I think it's working as expected.  Try the following example.

#+begin_src python
if a == 1:
    if b == 2:
        if c == 3:
            pass
        else:
#+end_src

If you enter the last "else:", Emacs displays "Closes if c == 3:".
This means that this "else:" corresponds to the "if c == 3:".

You can change the indentation by hitting the TAB key several times on
the else line.  Each time you do this, Emacs will display the
corresponding if statement.

For example, Emacs displays "Closes if b == 2:" when the "else:" is
indented as follows:

#+begin_src python
if a == 1:
    if b == 2:
        if c == 3:
            pass
    else:
#+end_src

Of course, in this case it is easy to find the corresponding if
statement.  However, in practice, many lines can go in between the if
statements and disappear from the screen.  This feature would be
useful in such cases.
