First you see active/passive. This means according to the configuration of the LSR it should send LDP unicast hellos to the specified IP address (active). It also is configured to accept and respond to LDP unicast hellos from the specified IP address (passive).
Second you see xmit/recv. This tells you, what the LSR does at the moment. Only "xmit" tells, that the LSR is sending hellos, but not receiving any. Only "recv" tells you, that there are hellos from the specified IP received, but no hellos sent (usually because the IP is not found in the routing table). The display of "xmit/recv" tells that hellos are sent and received, which is the prerequisit for a LDP TCP session.
AFAIK, the concept of active/passive in LDP has nothing to do with whether the hellos are targetted or using the multicast addresses. In both cases LDP has to chose one of the LSRs to be the active one, hence initiate the session, and the passive LSR waits for the active LSR to initiate the session. The active LSR is the LSR with the highest IP address for its transport connection.
