Section 4.9.5.1 says:

   o The combination of a (S,G) Prune and a (S,G,rpt) Join could
     possibly be used by a router to switch from receiving a particular
     source on the shortest-path tree back to receiving it on the shared
     tree (provided that the RPF neighbor for the shortest-path and
     shared trees is common).  However, Sparse-Mode PIM does not provide
     a mechanism for explicitly switching back to the shared tree.

It should say:

   o The combination of an (S,G) Prune and an (S,G,rpt) Join could
     possibly be used by a router to switch from receiving a particular
     source on the shortest-path tree back to receiving it on the shared
     tree (provided that the RPF neighbor for the shortest-path and
     shared trees is common).  However, Sparse-Mode PIM does not provide
     a mechanism for explicitly switching back to the shared tree.
