Its an editorial error where the 2 ft dimension should've been removed when the figure was modified and published. The original proposal showed doors on both sides of the hallway with a 2 ft inset the same as Figure 6.4.6.3.3.2 in NFPA 13R 2013 ed. I was told some committee members felt uncomfortable with a 2 ft inset on the same wall on which sidewall sprinklers were mounted.
