I think the point he is trying to get us to understand, without telling us is that we need to shorten our sets. He begins the article by saying that we should ovoid going to failure on every set. This is a commonly held idea. However, failure in this case has to do with the larger, faster motor units. So, when a lifter continues to put up reps after he has slowed down, the large motor units have become fatigued, even though the lifter has not gone to "failure". Therefore, the bottom line here is to put up heavy weight with fast paced sets, both eccentric and concentric. But, make sure to stop when your pace slows down. This enables you to work the large motor unit optimally without going to failure in every set.
That's what I got from doing a quick read through of the article.
