I had trouble understanding the reasoning of this example as well.
In our data model, the email would rather be a collection, and the
signature an element of it, rather than a specialization of it.
A specialization of "this email" would be, for example. the "printed
version on my desk", which *is* a specialization of "my thoughts on this
email thread".
Intuitively, I am having trouble coming up with a counterexample of the
transitivity of our specialization.
