Hmm, that's odd. As far as I know, the difference between the hg and git
DAG model can be summarized like this:

 * In git, leaves of the DAG must be assigned a name. If they don't have
   a name, they will be garbage collected. If they have a name, they are
   called a branch.

 * In hg, leaves of the DAG persist. If you want to remove them, you
   have to do so explicitly (hg strip), if you want them to have a name,
   you must do so explicitly (hg bookmark). A node of the DAG with a
   name is called a bookmark.

 * hg named branches have no equivalent in git. 

Does that help?


Best,
