They can certainly do that, I suppose. I've seen pictures of cannabis that was like the "arborists' art" things that people do to trees, stems growing together in geometric (etc.) designs. I even saw one that must have been tied into a (loose) knot as a seedling. You can merge multiple plants, too. And, of course, branches can root to the ground if they come into contact with it for any real length of time. That's one of the ways to slowly produce a clone that stays attached to the mother plant until it's all ready to go (and then the gardener cuts it loose). The other way being air layering, where a branch grows roots without having to be down on the ground.It appears to me that it's like a number of branches exploded from one site and merged together.
