Named branches are exclusive, they can't be a subset of each other ;)
Actually, they can. Take the example of the Mercurial repo itself. They fix bugs in the stable branch and add features in default. When they merge stable into default and commit, default becomes a superset of stable. That is to say, someone pulling default also gets the changesets from stable that are ancestors of the merge changset. Or in other words, if you check out default, you get all bug fixes from stable. HTH
