Comment Approval Message Showing to All Users

I’m using a custom function to output comments. It seems to work fine, however I’ve added the following notice for when comments are yet to be approved:
<p class="awaiting-approval">New comment is awaiting approval</p>

However, rather than this just showing to the comment author, it seems to be showing to everyone. Is WP supposed to use cookies to determine who the author was?

Here is the full code for the function if that helps:

Also, I’m calling the function like so:

$comments = get_comments(array(
		'post_id' => 9
	));

	// limit comments if comments displaying in sidebar

	if (is_page(9)) {
		$args = array(
			'callback' => 'theme_commentCustom'
		);
	} else {
		$args = array(
			'callback' => 'theme_commentCustom',
			'per_page' => 3
		);
	}

?>

<ul class="feed">
	<?php
		wp_list_comments( $args, $comments );
	?>
</ul>
