The rule is to establish that, yes. It's no biggie if it doesn't happen, but it just makes things easier. What people have been doing lately were instead telling the player that they sent, or will send, the replays immediately after the official was over...which is also fine.
The complaints that were made in the past were when people were doing this "winner saves the match" stuff...which only made things needlessly complicated.
Told you Ck!
