Include flag status by default

At the moment the flag status is not included:
if ($variables['after_flagging']) {
$inverse_action = ($action == 'flag' ? 'unflag' : 'flag');
$variables['message_text'] = $flag->get_label($inverse_action . '_message', $content_id);
$variables['flag_classes_array'][] = $variables['status'];
}

But I can't find any documentation about "after_flagging" ... can't we just have the flag status by default?
