I think you are right that it should be ⊂f/AgB.  I stand corrected.

But I was looking at the evaluation sequence just below the informal
description you quoted and after some reshaping and scalar expansion
it says:

Now I think this is an error and this statement should be simply omitted
because the subsequent description of how to form Z works for vectors too
and would result in an enclosed value, but this is where I got it from.
