His point is that (according to what he saw) Parry rating doesn't contribute appreciably to survivability, effectively being wasted itemization. If it's really wasted itemization, you're better off optimizing for damage as opposed to parry since, even if it's not your primary job as a tank, you're still contributing damage. Just because it's not your primary job doesn't mean that you shouldn't be looking for ways to optimize performance in your secondary functions.
