Yes, that's (unfortunately) correct.
I have (say) two flute parts that will be printed individually in parts. But in the score they should be combined (which is what \partcombine should be good for ...).
But for some reasons I have to enclose the flute parts in explicit voices, and this doesn't seem to work with \partcombine.
% fluteI
c'' {
c1 ~
}
two = \relative c'' {
c1
}
fluteI = \new Voice {
\one
\two
}
etc.
the \new Voice construct is necessary to enable the tie in this example.
I have no clue if I can get out of this situation with real hassles. Therefore I asked if there's a way to "extract" the plain music _expression_ out of \fluteI here.

it works just as it did without the "\new Voice". This could be from the simplicity of the example, but it makes me curious.
