Fred started shooting field archery, as was the thing to do back then. In field archery, you wanted a low hold so your point on was farther. They also tended to use multiple touch points, anchor under chin, kiss the string (some used a kisser button), tip of nose to string, string bisects aiming eye.
Those that used sights tended to those anchors so they could employ multiple pins out to maybe 80 meters or so. A higher hold would not allow that.
It was a different world.
That mode of aiming does not lend itself to hunting, although some kept doing it. A higher (on the face) anchor puts the arrow closer to the eye so you can aim quicker and better.
Fred could hold his thumb up like that. A friend in my archery club (early 70's) did the same. I can't even get my hand to bend around like that, much less doing it comfortably and repeatably.
You gotta do what works for you.
If your thumb is making your hand stand away from your face, maybe try anchoring a tad further back so the thumb is past your cheekbone ?
