Having a secondary display that could display background free or different backgrounds behind the same lyrics as the primary display. Also could choose to have video cues play only on the primary and not secondary displays.
This would primarily be useful for stage design matching (i.e. For a large central display and secondary smaller displays, different backgrounds could be used).
Another potential use is white lyrics over black background for luma keying, a lower-cost alternative to alpha keying for IMAG and broadcast purposes.
