Yes, that's essentially the gist of it (although the book claims it's all on-plan, KWIM?). After I followed it for about a month like I mentioned, I treated it more like a calorie-counting plan. I was about 1500 calories a day, and 250 of that was a "fun food" with pretty much no nutritional value at all (if you chose, you could always eat nutritionally but I always went the chocolate route).
