Apical dominance in the Norfolk Island pine

Walking around my parents' neighborhood in central Florida, I see a number of what I think are large (40 ft or more) Norfolk Island pine trees. About half of them are split some ways up the trunk into two or more tops about the same height. My question is about apical dominance. How could it happen that an additional shoot apical meristem would develop in the other fork(s) of the plant in a species with strong apical dominance like that one? What's the mechanism there? Scholarly articles and your own thoughts very welcome!
