The .ly file is very long and appears to be automatically-generated code, so 
let's ignore that.

The image looks like

  \new Staff  <<
    \new Voice \relative c'' {
      c a c b c c c b
    }
    \new Voice \relative c'' {
      g f g g g a g g
    }  >>

except with whole notes in place of quarter notes.  The whole notes are displaced in 
the same way as notes with stems would need to be displaced so that the stems do not 
collide.  The warning comes not for the notes that are displaced, but for the <f 
a> combination that has both stems in the same direction.

If you are using Lilypond, use \\ to setup the two voices automatically.  Using 
\new Voice explicitly, you need to specify yourself which voice is 'VoiceOne' 
(see the Lilypond manuals) to set the stem directions.  If you want to use 
denemo, though, you'll have to look at its docs are ask its developers how to 
get what you want.
