I don't see the problem? Real natural tree branches grow. If you move the branch to point somewhere else, then it's better/more accurately said that you changed the name to refer to a different branch. We can think of branches as the chains of commits; it's the names we give them that 'wander' both as we commit and if we move them to a different branch. But merging (as it were!) the concepts of branches and names for their tips is convenient, and often equivalent/inconsequential.
