That sounds like a very circumspect way to find this out.  Check out
lily/*-iterator.cc;  in particular, look for calls to

void Music_iterator::descend_to_child (Context *child_report)
void Music_iterator::set_context (..)

which explain some of the things you are seeing.

Note that contexts do not 'nest' as you claim in a message below.
Voice contexts cannot contain any other context.
