This sort of illustrates the problem of thinking size of bikes is seat tube length or some other frame dimension. Frame geometry and dimensions only matter when you know what other components are on that frame. The length of the seat post, the length of the stem, the reach of the handle bars. Other stuff too.
Frame geometry doesn't mean much for fit until you know what other stuff you are putting on it that will give you your actual position. It's the position of your contact points on the bike that matter. Where is your butt in relation the cranks and also your hands and how much lean do you want in your trunk. That is what matters for fit.
