Section 4.6.5 says:

       Rationale: This avoids keeping state alive on the (S,G) tree when
       only (*,G) downstream members are left.  Also, it avoids sending
       (S,G,rpt) joins to a router that is not on the (*,G) tree.  This
       behavior might be confusing although this specification does
       indicate that such a join should be dropped.

It should say:

       only (*,G) downstream members are left.  Also, it avoids sending
       (S,G,rpt) joins to a router that is not on the (*,G) tree.  This
