First time post, and I know this is an old trend, but just thought I would put add a few comments as most people who have responded have not picked up on one thing.
As pointed out the video of Faldo is from the 1992, but in the video Nick is not hitting a full shot, he is hitting a punch or knocked down shot. He was hitting a long iron, but if you look at the swing you can see the ball position is very far back, weight forward, the swing is only 3/4 and the follow through is also short, so it is understandable that people would see similarity between this swing and the what comes under the description of stack and tilt.
You can go on YouTube you can see more video footage of Faldo from the same day and you will see hit hitting more punch shots, full swings etc. The last iron shot he hit that day was also a 3 iron and you can see it was a full swing and what he would consider a normal swing.
I'm getting back into golf after being out for a few years, was a big big Faldo swing when I was young, and saw hit hit balls in the flesh and even ignoring the results, it was a great swing to watch when he was in his prime.
I have been fascinated by how golf has changed in the few years I was away, the new ball flight laws and the stack and tilt swing do go completely against what I thought was fact, but being an engineer and open minded I'm finding it very interesting.
