you are doing constructs of the form


  { %% !!

     \new Voice = foo { .. }
     \new Voice = bar { .. }

  } %% end!!


The sequential marked !! has an iterator, and it will descend to the
lowest context automatically, but does not look into << >> constructs.
Effectively, in this example, this will keep "foo" alive until the end
of the seq music marked "end!!"
