Where there is a clear cut between camera shots (e.g. "Court-Martial") one could speculate that the "in-universe" alignment could be different, but in "The Naked Time" we do see part of the Engineering Control Room from the outside and we do see the outside corridor from the inside the very next second.
A circular corridor outside of "The Naked Time" engine room isn't being debated in my response. It's the placement of the room at port or starboard side of the saucer that we have a difference of opinion and you'll find no visual evidence to support a conclusive right or wrong answer, IMO.
