Well I suppose it really does not matter too much but most of these types of systems have doors which use the pressure of the habitat to help hold the door against a seal.
The same as an emergency door of a plane cannot be opened in flight, these doors could not be opened accidentally or maliciously until the pressures were balanced if they opened inward.
It is just cosmetic inside the game of course.. and actually makes zero difference. So. Probably dont waste time changing it unless you have to hit that section over again anyhow for some reason.
