Continuity mistake: When Homer makes the food with the mix of Tom Collins mix, cloves and a pie crust you can see the labels on the Tom Collins mix and the cloves change between mixing the ingredients and after tasting them. Also the top on the Cloves bottle keeps changing through the scene. When Homer takes the bottle out of the fridge you can see a red top on it. When he sits down the top has disappeared and starts pouring the cloves. When the shot changes the red top is back and it disappears after that. (00:15:20)
Chosen answer: You're right--it's a character mistake, but an explainable one. Andy probably figured that because he was doing so much work for the Warden (accounting for dirty money, kickbacks, tax compliance, etc.), that the Warden would use his power to get Andy a new trial. Sounds like a fair trade--Andy makes sure there's no way for anyone to disover the illegality of the laundering, and the Warden gets Andy pardoned. What Andy didn't realize, however, was that the Warden didn't want to risk having Andy, after his pardon & release, reveal the details of the illegal schemes that were going on. So to make sure Andy got the message that he was going nowhere and would reveal nothing, he was give the two months in solitary confinement (as you know from the movie, of course).
