Eventually, and they won't become dominant if you pull them down below or level with other growing tips.The main tip (cola) on a plant will receive the majority of resources and energy. This is called apical dominance. If you cut that tip, the next two branches below that will become your main colas and will split the resources.
When you top a plant all the lower growth gets a bit of a boost as you've removed one of the sources of the hormones related to apical dominance, and the hormones which promote branch and shoot growth become dominant for a little while.
