Jj uses git's data model, that doesn't mean it uses git commands for everything under the hood. Creating a commit with jj doesn't move the branch tag automatically, whereas git does. That's what confused me with git, it didn't expose the internals enough, so even though I had read about the data structures, it never clicked what was changed when, because git did it under the hood.
