No no, they're the same field. It's replacing the bbcode version of itself with the HTML version of itself.

You would want to repeat it for a second profile field if you want to enable the bbcode for something else.

Ex:

$post[field15] = $parser->do_parse($post[field15], false, false, true, false, false, true);
$post[field18] = $parser->do_parse($post[field18], false, false, true, false, false, true);
