Well that was an error on my side. My code changed while I was writing 
the email.

It should be clear by now that Y has static and dynamic type CatA while 
W has static type CatA and dynamic type CatABC. It basically says that 
the  "(...)@CatABC" hides the "add" inside the parentheses. The whole 
construction for W is not an add-expression.
