Knute,
IMHO it is not that it cannot, rather it is that placement depends on whether the stem is extended up or extended down. The documentation has the stem extended from the bass, therefore the command is in the bass. In my MWE the stem was to extend down from the treble to the bass. And therefore, as William and Jean noted, the command needs to be in the treble voice.

So I am very fortunate to have your expertise. Can you please suggest a better wording that I can add to the documentation? Well, this is the first time I've heard that the \crossStaff shouldn't be applied to the lower notes. The documentation ( https://lilypond.org/doc/v2.24/Documentation/notation/common-notation-for-keyboards#cross_002dstaff-stems ) shows an example with the \crossStaff in the bass clef staff: \layout { \context { \PianoStaff \consists "Span_stem_engraver" } } { \new PianoStaff << \new Staff { <b d'>4 r d'16\> e'8. g8 r\! e'8 f' g'4 e'2 } \new Staff { \clef bass \voiceOne \autoBeamOff \crossStaff { <e g>4 e, g16 a8. c8} d \autoBeamOn g8 f g4 c2 } >> } -- Knute Snortum
