“Logical” is the word I’d use. I think the set itself was too big, or too long, to actually fit inside the Falcon “prop” seen in the Mos Eisley hangar. But it works well as a EU illustration/explanation of the Falcon’s layout.
As a side not; I find it funny that there’s only three beds in the same small room. Also doesn’t that imply that one of the characters in ANH had to sleep on the couch in the “rec-room” when they were going to Alderaan?
