That's because of the \\ only -- that creates two new Voice contexts,  
each different from the main one that existed before the <<>>.

What you *can* do is

    a b c\< d << { a b\! c d } \new Voice { g g g g } >>

and things will behave as desired -- the first {} is a continuation  
of the main Voice context, and only the \new {} is different/new. See  
"Instantiating new voices" in the docs for more info.

That would also work, but you don't have to remove the bar checks.

Hope this helps!
