That's normal.  The action for any form is always the current page,
unless someone sets $form['#action'] explicitly.  This works, because
when you submit the form (your form, or the search form) back to the
same URL, drupal_get_form() gets called again for that form, which in
turn checks if the form has been submitted, and handles the submission
if so.

At one point, the search form itself did explicitly set #action to work
around a bug - http://drupal.org/node/67648 - but this was eventually
removed in favour of a different fix.
