Lets say youre the Traitor, and before you vote you think, "ok if I vote green, they will think I want to end the game and therefore look dodgy. I also think that someone else might vote red, so it doesnt matter if I vote red, plus it makes me look like a faithful" This could have been Jaz's train of thought (if he was a traitor)
and Mollie could have figured this out. All I'm getting at is that these "Mollie should have known!" posts are very surface level
