There is priority in this. when they are fighting for the title then indeed they put all their strength for the sake of points and victory but when they succeed and have secured the trophy then in this case there are other things to pay attention to such as trying out several possible schemes for next season.
That's what I see now, even though in this case the bettors didn't expect it a bit, but they also didn't have a big reason to get 3 points after the trophy was obtained.
His main priority is to win trophies so every bit of his strength should be able to go towards their main objective for the season because they will be much better off winning before getting a trophy and relaxing after getting a trophy. I think it's a wise enough thing to do because the team doesn't need to fight when they are already champions, because the team also won't get anything better than the number of points when fighting after getting a trophy in a certain season.
