Yes, this is clearly a limitation of the << \\ >> construct: voices
within that construct are considered as voices both different as the
voice outside this construct.
This is not the case with
<< { \voiceOne ... }
  \new Voice { \voiceTwo ... } >>
since the first voice in this construct is considered as the
continuation of the voice outside the construct.

You can use \context Voice = "splitapart" for the second "exception"
voice (instead of \new ...).  So you have only 2 voices created.  ;-)

Actually there is a project to rewrite << \\ >> so it behaves like with
"explicitly created voice construction".
http://lists.gnu.org/archive/html/lilypond-devel/2009-09/msg00096.html

Let's hope this will be done, so for cases like this one explicitly
created voice construction won't be necessary.  And << \\ >> is a
considerably reduced clutter for that.  ;-p

I'm not used to write vocal scores, sorry.

Cheers,
