Not sure why you'd say that? The point of topping is to get more cola's...more yield!I wouldn't top a auto flowering plant. Their yields are already low enough already.
Autoflowering plants start budding based on age from seed, so the top would just start budding like it's mother, you basicly stop the the top from growing up for light and focus on roots when you top the plant.
