My example was deliberate. :-)
I am not very fond of that clause of the GPL myself. But it's worth noting
that it doesn't specify any particular text. Instead, it gives a rather
generic set of requirements. In a modified version, I can (must, in fact)
fulfill these requirements with an announcement which is quite different from
the one used on the original program. Furthermore, the announcement
requirements are directly related to the legal status of the distributed
program. So it's a very different case from GFDL-style Invariant Sections,
and does not correspond to my example.
