What's the significance of the Blue Hallway before the 'two door' room?

Is there any significance to the Blue Hallway that appears sometimes before the 'two doors' room at the start? And has anyone else seen this hallway and found out that significance?

This blue hallway (which is not directly at the start) is another random element of the game. It doesnt bring much except randomness in the game. Kind of like when you begin the game again and have a straight corridor to the 2 doors room.

I've read somewhere that this hallway was kind of a mandatory shortcut to unlock the Speed Run achievement.
