The talk defines a relation, "more expressive than", between
languages. As I'm sure you're aware, a relation between pairs of
elements of a set is sufficient to define an ordering of that
set. In this case, I believe it is entirely reasonable to refer
to the ordering so defined as "expressiveness", even if it is not
explicitly referred to by that name in the talk itself.
Also, I remind you that you are the one that brought the word
"expressiveness" into this discussion in the first place. In my
original post, you will note that I took care to use the term
"more expressive" to refer to the aforementioned relation.
