That seems to be an issue with the shifting mechanisms for simultaneous 
upwards-facing (\voiceOne, \voiceThree) voices.

Compare:

\new Staff {
 \voices 1,3,4 <<
    r4 \\
    { f'8 e' f' c' } \\
    { c'8 c' c' c' }
  >>
}

\new Staff {
 \voices 1,3,4 <<
    { g''8 g''8 g'' g'' } \\
    { f'8 e' f' c' } \\
    { c'8 c' c' c' }
  >>
}

\new Staff {
 \voices 1,3,4 <<
    { g''8 g''8 g'' g'' } \\
    { f'8 e' f' \tweak NoteColumn.force-hshift 0 c' } \\
    { c'8 c' c' c' }
  >>
}

I'm not sure if the force-hshift tweak is the definitive way to do it, 
but it also helps in your example.
