AIUI what's happening now is that \test is passed to NullVoice,
and so it doesn't appear in the output. However, there's a \new
Voice inside \test, and LP doesn't have anywhere to pass it, so
it instantiates a Staff for it, and prints it.
If you put the new voice into a variable, like:
polly = \new Voice {
\voiceTwo \magnifyMusic 0.8
{
r8 e e e e e e e |
}
}
you would still need to defer polly's interpretation, so
that \test only expands it when \test is passed to Staff
(1st score), or NullVoice (2nd score).
Then, before you create your second score, you can set:
polly = { }
to make it "disappear". (I don't know the jargon.)
Does that make sense?

David.
