If indeed the correct explanation for poor performance were that a resource has been depleted, then X shouldn’t matter.
Where X was any number of things that he shows does matter. But saying that you have limited resources to make decisions in no way claims that nothing else matters, so showing that other things matter doesn’t really bear any evidence against a theory of decision fatigue.
Be careful with the model of decision fatigue. See Robert Kurzban’s criticisms here: http://www.epjournal.net/blog/2011/08/willpower-is-not-a-resource/.
