Does the 1 hour reduction for Fire Sprinkler System apply to NFPA 101: 38.1.3.2.1?

Does the 1 hour reduction in fire resistance rating, offered in NFPA 101, Table 6.1.14.4.1(a), apply to the fire barrier minimum 2 hour fire resistance rating required in NFPA 101, 38.1.3.2.1, 2012 ed., for a combined business and parking structure? 38.1.3.2.1 calls for a 2 hour fire separation between the parking structure and the business occupancy. I am being told that the 1 hour reduction can be applied in this situation if the business and parking structure are fully fire sprinklered but it does not specify that reduction in this section.
