Marketpress Javascript CDATA Commenting

I was doing some prep/investigation on a web site and I noticed that the MP JavaScript uses the new style of commenting around CDATA:

<script type='text/javascript'>
/* <![CDATA[ */
var MP_Ajax = {
	ajaxUrl: "http://domain.com/wp-admin/admin-ajax.php",
	emptyCartMsg: "Are you sure you want to remove all items from your cart?",
	successMsg: "Item(s) Added!",
	imgUrl: "http://domain.com/wp-content/plugins/marketpress/marketpress-includes/images/loading.gif",
	addingMsg: "Adding to your cart...",
	outMsg: "Out of Stock"
};
/* ]]> */
</script>

Wouldn't it make more sense to use the mixed commenting as mentioned in the article linked to below?

It's potentially an issue waiting to bite someone using older browsers...
