Correct, but NFPA 13 states to use a sidewall sprinkler and they are not allowed for Extra Hazard. Thus, one could assume the committee knew what is what doing and was stating an ordinary hazard design was acceptable. The Annex reference being quoted by the AHJ is not enforceable.

Ideally, the sprinklers should be located near the side of the pit below the elevator doors, where most debris accumulates. However, care should be taken that the sprinkler location does not interfere with the elevator toe guard, which extends below the face of the door opening." No mention of combustible hydraulic fluid. Extra Hazard??????? Just thinking out loud!
