"Packets and frames sourced from inside the fabric and destined outside of the fabric are de-encapsulated by the border node"(not the edge node)

The PIM mode that uses a shared tree only is the sparse mode. In sparse mode, PIM routers build a shared tree for multicast traffic, which is shared among all of the routers in the multicast domain. The shared tree is built from the source routers to the rendezvous point (RP) and then from the RP to the receivers. The advantage of sparse mode is that it requires less state information on the routers.
