Yeah, I love jj, but I'm not a fan of that naming. It threw me for a loop for the first couple months. I'm not sure what happens, but I suspect a merge would create a single merge commit with the tips of the parents' histories, and then add new commits from there on. A split is probably conceptually similar to making two new branches, except each of the new commits gets one of the branch tips. Really just guessing here, I have no idea if that's how it works, or if they share commits or not.
