I really can't see how - the acute angle is pretty obvious, which is why it first peeked my attention.
It looks to me that the small wall with the gooseneck viewer on it is at a 90 degree angle to the wall with the door. And it looks to me that the wall with the "kiosk" is at a 90 degree angle to the small gooseneck viewer wall. It seems the only thing that is differing in LTBYLB is the *back* wall. It is not perpendicular to the wall with the door. Compare the LTBYLB shot with a very similar shot from Lincoln's POV on the transporter pad in Savage Curtain."
