Well, this is indeed something that you should watch out for, but it's
also true that committing on top of a past changeset is a very useful
feature.  For example fixing a bug directly on top of the changeset that
introduced it is a neat feature of a graph-based history :)

Before *push* you do get a warning when multiple heads are created.  So
you can still rebase/merge or look at the local heads before pushing.
