Those two little spots will grow to be branches. They will become the top of your plant, but it will not continue to grow upward to create anything new. Basically, cutting (topping) your plant there arrests its upward growth and causes the plant to expend its efforts in making the plant grow out, and not up. Eventually those two will develop bud sites of there own during the flowering stretch and begin to produce bud. Good job, and best of luck with the rest of your grow!!
