Section 4.5.4 says:

   On unnumbered interfaces on point-to-point links, the router's
   address should be the same as the source address it chose for the
   Hello message it sent over that interface.  However, on point-to-
   point links we also recommend that PIM Join/Prune messages with an
   upstream neighbor address field of all zeros are also accepted.

It should say:

   Hello message it sent over that interface.  However, on point-to-
   point links we also RECOMMEND that PIM Join/Prune messages with an
