Probably that is how most people use the word: "re-potting" is the broadest word covering any combination of:
1. move to bigger pot (with or without disturbing the root ball)
2. replace all or most of the potting mix IN the root ball
3. root prune (and return to a bigger, smaller or same-size pot)
But I like using many specific terms like "up-potting", "total soil replacement", and "root pruning".
I guess trying to change the meaning of "re-potting" to be more specific and mean "total soil replacement" is revisionism, or at least Humpty-Dumpty-ism ("words mean whatever I say they mean", which doesn't help communication unless everyone agrees on the meaning).
