Notice as he got older he moved the ball further back. He went from fading the ball to drawing it. There’s a great clip of Lee talking to Tiger and Charlie on the range at last year’s PNC about wedge shots and you can here Tiger say to Charlie, “this is why you hit draws on your wedges now”. Lee still will hold off the wedges when he wants some brakes, but any club longer he plays a draw.

It's just a hold release. Less power and a little more accurate. That's how to hit a pitch and run just a much bigger version. Worked out pretty well for him. Few on tour release this way regularly. You will never see this release in long drive competitions or in the longest hitters on tour. Trevino was known for his accuracy and especially wedge play. His release is a hint as to why. Not the miracle secret of the golf swing.
