I agree with Steve's reasoning. However, the wording of A.8.15.3.2.1 "Sprinklers at each floor level landing should be positioned to protect both the floor level landing and any intermediate landing." leads me to believe it's not the intent to install sprinklers beneath intermediate landings (except the lowest one per 8.15.3.1.3).

Splitting hairs over limited combustibility when there's exposed wood in any compartment isn't usually a fruitful exchange with most fire officials and based on your description, my first instinct is that these should be sprinklered per the prescription in 13, i.e. sprinklers at both sets of landings.
