Is he trying to move the 150' rule outside, in a scenario where FHVs are not present?
NFPA 14 (2010) 7.3.2.2 Where the most remote portion of a nonsprinklered floor or story is located in excess of 150 ft (45.7 m) of travel distance from a required exit containing or adjacent to a hose connection or the most remote portion of a sprinklered floor or story is located in excess of 200 ft (61 m) of travel distance from a required exit containing or adjacent to a hose connection, additional hose connections shall be provided, in approved locations, where required by the local fire department or the AHJ. IBC (2012) 905.4.6. Where the most remote portion of a nonsprinklered floor or story is more than 150 feet (45 720 mm) from a hose connection or the most remote portion of a sprinklered floor or story is more than 200 feet (60 960 mm) from a hose connection, the fire code official is authorized to require that additional hose connections be provided in approved locations. For the hose lay vs. crow fly diagram, see NFPA 14:A.7.3.2(a) for an example.

This from a Fire Marshal for a large University in AZ. We were having trouble locating hose valves in the one story area of the building. There are only two stairs in the building and they are more than 200 ft. from parts of the gymnasium. We reviewed the code and offered a credit to delete the standpipe system because we didn't think it was required. This the response from the FM. He wants all interior points to be with 150 feet from where they park a fire truck. "If you send a too scale plan from where fire trucks will be at all points of entry to the building and can show that nothing is more than 150' I will entertain the suggestion of no standpipes. I have seen everything that ****** has been shown and it is not represented well. This includes the existing building since the existing building had adequate coverage and did not need a standpipe before the add-on. Now that there is an add-on where there is no access at the center point it affects both the new and old and we need assurance with a too scale drawing from fire truck to all areas of all floors. Discussing it does not solve anything until you can also prove it on paper too scale "as the hose lays and not the crow flys." I have difficulty finding a way to talk to someone like this.
