Yeah, I'd have expected that to be the significance of c.

I think that my patch on issue 4569 likely cures the problem.  Curing
the symptom is likely achieved by starting with a context change
regardless of whether one is necessary.  No idea whether that's what
your patch would be doing.  I think that the _problem_ is completely
leaving the original context hierarchy (which almost magically is
avoided with other start notes by _starting_ with the first context
change which likely is performed by the autochange iterator _before_ any
simultaneous creation of contexts).
