Section 7.2.2.4 says:

   If the received Inter-AS A-D route carries the PMSI Tunnel attribute
   with the Tunnel Identifier set to RSVP-TE P2MP LSP, then the ASBR
   that originated the route MUST establish an RSVP-TE P2MP LSP with the
   local PE/ASBR as a leaf.  This LSP MAY have been established before
   the local PE/ASBR receives the route, or it MAY be established after
   the local PE receives the route.

It should say:

   If the received Inter-AS A-D route carries the PMSI Tunnel attribute
   with the Tunnel Type set to RSVP-TE P2MP LSP, then the ASBR
   that originated the route MUST establish an RSVP-TE P2MP LSP with the
   local PE/ASBR as a leaf.  This LSP MAY have been established before
   the local PE/ASBR receives the route, or it MAY be established after
   the local PE receives the route.

Notes:

There is a defined Tunnel Type for RSVP-TE P2MP LSP, whereas the Tunnel Identifier field has a more complicated structure that depends on the Tunnel Type.

Section 4.2 says:

Furthermore, if the local PE uses RSVP-TE P2MP LSP for sending
(multicast) traffic, originated by VPLS sites connected to the PE, to
the sites attached to other PEs, then the local PE MUST use the
Originating Router’s IP Address information carried in the Intra-AS
A-D route to add the PE, that originated the route, as a leaf node to
the LSP. This MUST be done irrespective of whether or not the
received Intra-AS A-D route carries the PMSI Tunnel attribute.

It should say:

Furthermore, if the local PE uses RSVP-TE P2MP LSP for sending
(multicast) traffic, originated by VPLS sites connected to the PE, to
the sites attached to other PEs, then the local PE MUST use the
BGP Next-Hop IP Address carried in the Intra-AS
A-D route to add the PE, that originated the route, as a leaf node to
the LSP. This MUST be done irrespective of whether or not the
received Intra-AS A-D route carries the PMSI Tunnel attribute.

Notes:

There is no such field as the Origination Router's IP Address in any VPLS A-D routes (RFC4761, RFC6074). For Intra-AS cases the BGP NH IP address can be used for the leaf tracking.
