The theory behind this is that your body adapts to the calories you take in and learns to use whatever you give it most efficiently so by cycling or shifting your calories you are not allowing your body to adapt to a set number. Think about it this way, in the past when you were overeating you may have been eating an additional 500-1000 calories a day above what you were burning for your basic metabolic rate. At that pace you should have been gaining 1-2 lbs a week for a total of 50-100 lbs a year, but I'm sure for most of us that didn't happen. It's because your body adapted to the excess calories and burned more because it was given more. Of course it didn't/couldn't burn all the excess calories so that is why you slowly gain the weight over the course of the year, maybe 10-25 lbs. So it works the other way also - if you cut your calories to less than your basic metabolic rate, your body will eventually adapt and burn less calories to be more in line with what you are taking in. That can really slow down the weight loss.
The only way you can go into survival mode is with 3+ days of very low calorie eating. With the cycling plan, you are only eating low for a day or maybe two in a row and then you are back to moderate or high.

I don't think 150 calories is enough of a change to affect the body's adaptation to the caloric intake amount. I think it needs to be at least 200-300 calories different from day to day. Personally, I think the larger spike from the high day to a moderate to a low is very effective. I did a high day on Saturday, moderate on Sunday, and low on Monday and I lost 2 lbs. from Sunday to Tuesday. Prior to that I haven't lost any weight for over a week.
That being said, I think everyone has to work it out to best suit their own needs. For some, they may be able to eat the same number of calories every day and still lose several pounds a week. For others, the cycling works. Even within the cycling, some may find success with a smaller range of calorie shifts, and others with the larger range. Test it out and see what works for you.
