"In the first, two different anonymous array references are being constructed. In the second, ..."

So how can we use this concise & convenient "x 2" syntax to generate the former?

I think you understand this already, so I'll answer just for the sake of completeness: You can't. The  x operator (see perlop) makes exact copies either of the elements of a list, the copies of which form another list, or of a string | a scalar, which is a string or stringized "thing" (number, reference, whatever), the copies of which are then contatenated together. And it's not possible to get different things if you're making exact copies of a thing (if you're doing it right).
