That's a misdiagnosis of the effect. The original version _has_ two separate Voice context. The difference is that it also has \voiceOne and \voiceTwo implied. If you write << \new Voice \with \voiceOne { a'4 } \\ \new Voice \with \voiceTwo { a' } >> the results are the same (and \\ which indicates the counted voice separation becomes redundant). Whether explicit or implied, the \voiceOne / \voiceTwo is what causes stem directions to differ and noteheads to be available for merging instead of collision resolution. -- David Kastrup
