His tips are very good. I also like the book "Breakthrough Swimming". It's really amazing how the techniques change/improve. About 8 years ago I was taking "triathlon" swim lessons and they were showing things unveiled at the recent olympics. I went from being a slow swimmer to one of the faster ones. Incidentally, as a kid I was a lifeguard and even taught some swim lessons. I developed a fear of water after nearly drowning saving someone in the ocean and took up triathlons to get over it. In general I think people try to swim too fast and get out of breath. They don't "feel" the water to sense when they are gliding or impeding the motion. I' especially impressed the author mentioned reaching down further than you expect because that really helps you get your feet up and reduce your "frontal area".
