After Stephanie is murdered, when Mort shouts to run for their lives, the crowd exits the dining room and they turn right, then everyone runs for the double front doors, opposite the staircase. This means the windows behind the arm chair at the head of the table are at the back of the house, but later when they capture Tom behind that chair, the shot moves backwards through the window and it's now at the front of the house, beside the double front doors. (00:10:50 - 00:37:30)

After Tom is accused of being the murderer, when he's captured in the dining room they're all behind the arm chair as they crack a joke about Adrien Brody.
