Why not? Or at least, why would the former not be understood as
the latter?

Why would you want to claim that there is only one, then?

This has been superseded by later discussion.

It is unfortunate that the prescription was left in this unsatisfactory
state. It's unfortunate that such an inadequate prescription was all
we had to go on for ten years.

I was using your own gloss.

It depends. Supposing the current state of discussion of the gadri
system to be the final prescription, then one could deduce from that
that "pai broda" would be meaningless. But I am confident you could
find a way to argue that the deduction wasn't sanctioned by the
prescription and was therefore invalid.

We can talk about one member of an ordered pair, or about two ordered
pairs. So neither "ordered pair" nor "member of ordered pair" is
an example where only one number can conceivably serve as a quantifier.
