The polyps on the lower hidden branches of the pocillopora tend to loose colour and eventually die as the rest of the colony grows. But since that section was busted apart it now receives light in areas that were becoming overgrown. So I wouldn't necessarily call it growth, more like renewed life for those lower branches. That coral probably grows at a rate of 1/16" per week for me which is pretty good but those green star polyps will dominate your tank faster if left unchecked.
