Why FAQ has help text?

In faq.module, a help text is introduced:

<?php
case "node/add/faq":
  return t("Add a question and answer to a FAQ list.");
?>

Why is this here? The same text can be added from Drupal UI as submission guideline. The problem with this approach is that it cannot be disabled and will show alongside with the submission guideline. I propose that those lines should be removed and maybe find a way to add them as default value for the submission guideline.
