Here is the output after making \displayLilyMusic stupid about
\addlyrics and somewhat more \verbose about the result of \relative:

altoOneVoice = \relative {
   d'2\melisma e4\melismaEnd cis
}

altoTwoVoices = \relative {
    <<
      { d'2\melisma e4\melismaEnd cis }
      \new Voice { \voiceTwo s1 }
    >>
}

altText = \lyricmode {
    side, sit
}

\markup \column { "One voice in a music variable" "(center-aligned melisma)" }
\score {
  \displayLilyMusic
    <<
      \new Staff \altoOneVoice
      \addlyrics \altText
    >>
}

% same music as above, but explicitly written out in the \score block
\markup \column { "One voice explicitly written out in \score block" 
"(left-aligned melisma)" }
\score {
  \displayLilyMusic
    <<
      \new Staff \relative {
        d'2\melisma e4\melismaEnd cis
      }
      \addlyrics \altText
    >>
}
