Here are two pine trees why they have changed their shapes? The second one I call it snake pine tree.
In both cases, there might have been something laying across the branch or seedling, e.g. a fallen log that's now gone, that caused the growth pattern... ?
First one top was damaged, causing it to fork. Second one seedling came up with/near another, larger one, grew around it into the sun.
I agree with abgardeneer. There must have been something obstructing the normal growth of both trees, a fallen log or a branch of another tree, that no longer exists. By the way, there is no forking in the first tree. What could be mistakingly taken as a branch is in fact a trunk of another tree growing behind. I have also never seen any trees growing around one another into the sun (especially if they grow in enough sun already).
I'd agree with Ron B. In the first one, a likely cause of the damage was a pine shoot moth killing the lead shoot and then a side branch taking over. But other causes are possible.
