He is in not talking about a loop, he is talking about going from fingers to a release aid. And by the way when you add a loop it changes your string angle and may very well effect how the bow is in relationship to touching your nose and mouth at full draw. So in order to get it back to the same point you would have to draw it back a bit farther. Because of the string angle the same point on the string will be farther away from your face. And if you were already anchoring with your knuckle in the back of your jaw and added a loop it would move your hand back farther. How much depends on the length of the loop. It would be possible to get your thumb on your neck from there. Some people don't anchor with the string on thier nose either, they do it with it beside thier nose, and use the face as an anchor point. Adding a loop would change this, unless you shortened the draw to make up for it.

And that picture doesn't look right to me. It looks like his draw is still a bit long. His hand is back too far ( he could easily put his thumb on his neck by the way), left shoulder looks a bit high, and he is bending his head down into the string a litle bit to touch his nose. Not to mention his hand is just sort of hanging out there, not touching his face anywhere. He is wasting what could be another anchor point. It's not that bad, but it could be better. Actually the more I look at that picure, the draw length on the bow isn't bad (I wish I could see more of him), as far as the power stoke goes. His release is just too long, and I would personally ditch the loop. This is a good example of why a loop isn't good for every person and set up. Beetween the loop and the release he is too stretched out. Which is the same thing as having too long of a draw length. It's not always what the bow is set at, it's a combination of all the equipment you use. Sometimes not using a loop makes it easier and more comfortable to get the string in the right place on your face, or puts your hand in a better position on your face. I don't think the benefits of a string loop outweigh the benefits of having the bow fit you better. Alot of it depends on axle to axle and your facial structure.
