In the Documentation all the examples of NullVoice use \lyricsto. I don't
know if there's a specific reason.
I can find only this warning:

The NullVoice context must be inside a Staff context, and should only
contain notes that are already being displayed in that staff, and in the
same octave. Otherwise the NullVoice may interact with the printed voices
in unexpected ways. For example, arbitrary notes in the NullVoice may cause
accidentals to appear (or disappear) on the staff.
