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.
