Is my landlord right about air circulation & mold prevention?

Landlord is very insistent that if we don't open our bathroom window a particular way, the air will not circulate and the mold will take over and also there will be doom. Does he know what he's talking about?

Our bathroom: a small room with no ventilation fan and a single average-sized double-hung window with a thin plastic shade. After showers we generally raise the shade, open the top part of the window, and leave the (frosted) bottom part of the window closed, which I've always thought allowed us the privacy to be naked in our bathroom post-shower while still providing enough ventilation for the bathroom to dry out. The landlord insists that we absolutely must open both the top and bottom parts of the window, otherwise the air won't circulate. I'm not entirely sure that a) that's how air circulation actually works or b) the air needs to "circulate" in order to prevent mold.
Full disclosure: I'm also a little annoyed that following his instructions means that anyone walking by the bathroom window will be able to clearly see us in the bathroom, and I really don't want to have to put clothes on immediately post-shower or try to find somewhere else besides the bathroom in our tiny apartment to get ready. But if he's right I'm willing to make the sacrifice, because there is a minor shower scum/mold? problem that we keep under control with scrubbing, and I don't want it to get worse.
So, AskMe physicists and bathroom mold experts, is our landlord right? Will opening both parts of the window help the air circulate and thus better prevent mold?
