My point I think is that the structure is the structure of the voice,
not the structure of the staff.  Which is why, BTW, the MIDI repeats
don't unfold.

Visibly the structure voice shows the repeats, but the repeats aren't
actually in the music voice.


So when you unfold you get:
   <<
     \music
     { \structure \structure \structure }
   >>

t can't merge them in the PDF either.  But when it prints them as
repeat symbols, you can't tell from the printout.

Try this:
---
\version "2.18.0"

music= <<
    \new Staff <<
      \new Voice \relative c' { c4 c c c }
      \new Voice \relative c' { \repeat volta 2 { s1 }}
    >>
>>

\score {
  \music
}

\score {
  \unfoldRepeats \music
}


---
And look at the PDF.  The second system shows the unfolded structure.
