Surfing from the tail necessary to better surfing?

I read an article yesterday that grouped surfers as those who surfed from the middle and those who surfed from the tail. The author basically said the sweet spot of a surfboard is pretty far back on the tail and is the correct stance where your back foot is over the fins. It almost sounded from the article that once you figure this out and able to perform it, you will immediately increase your skill level.The author says obviously you can shift your position but this should be the foundation. Is this just an advice for shortboarders and also if you are lying pretty close to the front of the surfboard while paddling, are you supposed to make the adjustment to stand close to the tail at the pop up?
