Note again that the entry floor color is more muted than the color of the floor by the Order; dustier, maybe, or more worn-down. Hardly proof of Team Evil's tunnel being connected directly to the entrance.
Then the dead end must get as much traffic as the entrance door - that's possible but it seems more likely that the dead end is part of the same tunnel as Xykon et al are in, with the same colored rock, and the entrance immediately in front of the door has been deliberately colored the same by Serini to avoid making the teleporter obvious (but no need to recolor the area oots are in which is past the teleporter).
