I think we may be working with different definitions of what yo-yo dieting is. Yo-yo dieting isn't just bouncing back and forth between induction levels of carb and maintainance levels of carb, although, as Dr. Atkins points out in his book, it can lead to that if you use it as a quick fix for weight gain when you go off the diet for a period of time over and over. One of the examples he gives as an abuse of induction is those that low carb during the week and then eat anything and everything they want to on the weekends only to go back on induction again when the weekend is over. Yo-yo dieting is repeatedly losing weight only to gain it back again when you go off the diet you used to lose weight hence the term "yo-yo"; your weight goes down, then it goes back up again, then it goes down, then it goes back up again, etc...
