The track will simply be reported only after the player becomes master.
Tracks will be smartly marked as playing following rules:
The track that has been in the play state with the CDJ in the "on air" state for the longest period of time (allowing for a configurable length of interruption with allowedInterruptBeats) is considered to be the active track that incoming tracks will be compared against.
A incoming track will immediately be reported as nowPlaying if it is on air, playing, and the last active track has been cued.
A incoming track will be reported as nowPlaying if the active track has not been on air or has not been playing for the configured allowedInterruptBeats.
A incoming track will be reported as nowPlaying if it has played consecutively (with allowedInterruptBeats honored for the incoming track) for the configured beatsUntilReported.
Tracks will not be reported after the beatsUntilReported AND will ONLY be reported if the other track has gone into a non-playing play state, or taken off air (when useOnAirStatus is enabled).
Mixstatus reporting modes specify how the mixstatus processor will determine when a new track is 'now playing'.
