Heading back will stimulate more new growing points. It is a known fact that the terminal bud secrete a growth-inhibiting chemical which move down to the lateral buds. These chemicals prevent the new lateral buds from growing, when cutting back the chemical is no longer available so the lateral buds start to grow.
