How does segment-by-segment clearing of miles+copay work when the cost is different?

The only discussion I can find is this thread from almost 10 years ago. I'd like to check on the up-to-date answer. Quoting the OP:

The outbound flight does not have any inventory right now, but I will put her in for the upgrade on that. My question is on the inbound flight as it does not have any inventory on the CDG-JFK leg, but does have C inventory in the JFK-LAX leg. I fly that route often and the A32 business class is a nice product (although the 777-300 business class = A32 first class) and would like to get that segment confirmed if possible.

Is it possible to upgrade just the domestic leg and if so would it be just the standard miles + copay (i.e. 15,000 + $75)? If so, can I still put in for the entire leg and just pay the difference if it clears (25,000 + $350 less the 15,000 + $75 = 10,000 + $275)? What I want to avoid is paying both miles + copay, but not sure what else to do in an effort to confirm as much as possible right now.

Is this (still) true? I note that AA says (under "Changing mileage upgrade awards"):
If your plans change, you can contact Reservations to change your mileage upgrade award. There’s no fee to change your mileage upgrade award, but you may need to redeem more miles or pay the difference, depending on the new award price.
This makes it sound like, at least nowadays, OP could indeed plan on paying only an "add-collect" of 10k + $275 for CDG-JFK. Can anyone confirm? Was this an under-the-radar customer-friendly policy change?

Continuing with the response for the sake of completeness:

So total out of pocket for the return would be 25k miles + $350 (int'l co-pay) + $75 (original domestic co-pay) + $150 (redeposit fee).
I think there is no longer a redeposit fee, but the bigger issue I see with this strategy is that if you cancel the JFK-LAX upgrade, there is no reason to expect that C space will reappear on that flight to allow reconfirming as part of CDG-JFK-LAX. So I don't consider this a viable option.

Is this even possible? I.e., does (or did) AA even have the ability to charge 25k + $350 when clearing only JFK-LAX, just because the pax wants to "prepay" for the waitlisted CDG-JFK?
