It's not silly if you understand the point behind it.
When you go to the movies, usually the screen you watch the movie on fills a certain degree of your peripheral vision. What they've done is taken that perceived field of horizontal vision and put it in a formula that will let the TV you watch fill your peripheral vision to that same degree.
Also, there is a functional difference between the tvs we used to watch 30 years ago and today. With the advent of full HD (1080p), on screens of certain sizes and at certain viewing distances, you can see amazing detail. But, should you get a little bit smaller TV or sit a little bit further away, the human eye can't resolve the detail that your TV and Blu-ray player can reproduce.
So, in the interest of getting what you paid for, and reproducing the movie experience at home (hence the clever moniker "home theater") sit between 7' to 9' to see the best detail on that 55" TV you're considering. You'll have fun. I'm also a big believer in the power of the first impression. For your first movie on the set, pick a title that was mastered right and rated as a reference quality title. "Dark Knight" was mine. I'll NEVER forget it. And don't forget to pick up your jaw off the floor.
