It would not automatically revert back on the checkout success, but you could add the reverse code on the checkout success page, or make sure the redirect to the checkout success does it with a full url link that includes "http://".
The reverse code would look like:
<?php if(((isset($_SERVER['HTTPS']))) && ($_SERVER['HTTPS'] != "") || ($_SERVER['HTTPS'] == "on"))header("Location: http://" . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']); ?>
