Each room occurs two times, but there is always a door between them. (This checkpoint seems to have been made before the start and end flags were introduced.) It looks as if it dates back to a in-between pre-final and final style. (Look at the square door! My graphics are on medium...)

The lighter/first of the two rooms is called deathstar_corridor and the darker/last is deathstar_trench.
