Are two step microwave cooking instructions ever necessary?

Most frozen, heat & serve food items have microwave instructions like "Microwave for four minutes, rotate, and cook another minute." I suspect it's just the manufacturer looking to show that the food is somehow better quality than if the instructions are just "microwave for 5 minutes." Sort of like the frozen food trucks that supply chain restaurants that have pictures of chefs on the trailer. lmao. Anyway, I always skip the intermediate microwave step. Does anyone think they make a difference?
