It seems the Rest 'direction overrides get reset by parsing the other
voice somehow.
However the following \restUp cludge is a workaround:
restUp = {
\override Stem #'direction =
#(lambda (grob)
(if (ly:grob? (ly:grob-object (ly:grob-parent grob X) 'rest)) 1 -1 ))
}
restN = {
\revert Stem #'direction
}
musicA = \relative c' {r8 <c' c'> r <c c'>}
musicB = \relative c' {g4 g}
\score {
\new Staff {
<<
\new Voice { \voiceTwo {\restUp \musicA } {\restN \musicA }}
\new Voice { \voiceOne { \musicB } { \musicB }}
>>
}
\layout { }
}
