I’m no arborist, but if you look at it, there was considerable rot evident. Truth be told, the tree should have been taken down a while back. The reason is because of what’s known as a “split leader”, or a V shape twin trunk growth. This allows for organic matter to build over the years and hold moisture.
Even healthy looking, strong trees sometimes just drop branches or fall over, but that particular tree was an accident waiting to happen. Careful drop pruning when young prevents this, trees that grow in a competitive forest environment sort of do this on their own to some degree, though not split leaders.
One thing people don’t quite grok, branches don’t get higher off the ground as the tree grows. Pruning allows for a better shape, better health, and more sunlight on the turf.
You’d be taking down a lot of live oaks and chinkapins and Deep South magnolias which grow a bit east and west and even reroot on occasion if you followed that strictly
