Those 4 bets are clearly not the same bet. "who will win the rest of the match" is not the same bet as "full time result". They just decided that there is no God and it's not worth it for them. But people are not stupid. And it will hurt them for sure.
Strictly speaking you are right, and even the odds are different so bets are not identical, but I think you should be honest and say that you wanted to game their system and rules
