Re: In divisi lyrics, \skip in the top line skips two notes and causes bottom line to skip one note

[Edward Usher]

Ah, looks I misappropriated code that was intended for multiple verses.  So my revised question would be about

%%%%%%%%%%%%%%%
\version "2.18.2"
\score {
  <<
    \new Staff {
      \new Voice = "melody" {
    \time 3/4
    \repeat volta 2 {
      c'4 c'4 c'4 | c'4 c'4 c'4 | c'2. |
    }
      }
    }
    \new Lyrics \lyricsto "melody" {
      <<
    { a \skip 1 c }
    \new Lyrics {
      \set associatedVoice = "melody"
      a b c d
    }
      >>
    }
  >>
}
%%%%%%%%%%%%%%%

which is based on the fourth and fifth examples at http://lilypond.org/doc/v2.19/Documentation/notation/techniques-specific-to-lyrics.en.html#lyrics-and-repeats.
