How embarrassing ... I tested the other parts of the example, but not that.

It's trying to describe things a step at a time.  If we collapsed these
two parts together I think it might be too complex.  We could change
the wording a bit, or change the step-3 stuff to ALTER TABLE ADD
CONSTRAINT.

That might be good in a real case, but I think it would just complicate
the example ...
