Description (partial)

PTP session is not formed with the master if the path is MPLS.

This is seen when ASR920 is acting as MPLS PHP node and the slave node advertises implicit-null label for PTP loopback for peering with the master. This is not seen if slave node advertises explicit-null label to ASR920 sitting as PHP.
