20-3 tells us who must replace it and it doesn't include the opponent or opponent's partner.
Doesn't it include the person who lifted it?
The opponent's partner did not put it down it from where he picked it up but somewhere else.
So you must be saying a ball moved by another ball is not replaced but placed in every case, because no matter who does it, it will never be put back in the spot where it was picked up. But the way I read you, that will always be "placing" because it is never returned to where it was when picked up.
