Can someone please tell me why we do `if (isset($_POST['remember'])) $stored[3] = true;` when a user fails to comment?

(`$stored` is: `array($_POST['name'], $_POST['email'], $website, $_POST['comment'], false);`)

I ran into that question a while back - hacked a workaround - but never got an answer. I'm working with a similar issue today, and would really like to know if this is an erroneous line of code, or if there's a reason for setting the comment data to "1"...

Thanks!

Updating for completeness: is has been confirmed an error. More information in this discussion on trac.
