Comment #3 on issue 709 by address@hidden: Simultaneous simple expressions  
affected to a same Staff collide by default.
http://code.google.com/p/lilypond/issues/detail?id=709

The problem here is that the way implicit contexts are created from within  
parallel music leads to a confusing result: two separate voices with  
material intended to be combined.  I don't quite agree with comment #1  
since I consider

\new Staff { << { \voiceOne c'8 } { \voiceTwo d' } >> }

to be almost breathtakingly flippant in its assumption that its input will  
end up in two different voices.

Personally, I would consider it reasonable if << >> did not start an  
implicit voice of its own for every simultaneous part.  However, given the  
dynamics of iteration and context creation, changing this behavior might be  
trickier than expected.

Also, one sideeffect would be that with
\new StaffGroup <<
  \context Staff { ... }
  \context Staff { ... }
  \context Staff { ... }

all material would end up in the same Staff.  Though it probably already  
does (judging from issue 3290).

At any rate, the issue as reported is not valid.  The original problem  
might be avoided with explicit voice contexts, and the whole topic of  
implicit voice creation might want revisiting in a broader context.  This  
particular symptom can't be cured in isolation.  See also issue 641 for a  
similar problem.
