Utilization of couplings on a service Mast

Recently I replaced added a service disconnect/meter socket to an existing system and added new SE to the utility as it was to short for the new panel. The inspector noticed there was a coupling on the old 50 year old+ service mast and said it needed to be removed. First, if I removed it this would violate the PUD's 18" rule to the roof, but secondly, doesn't the NEC 230.28 Masts as Supports allow for coupling if there is a support to the roof above it such as guy wires? "where the coupling is located above the last point of securement to the building".IE Utilization of couplings for a mast are permitted only below the point the mast is braced, secured, or supported.

IMO the inspector would cite 230.28(B). The issue is the part in bold and as to whether or not braces or guys wires comply with that requirement.

230.28(B) Attachment. Service-drop or overhead service conductors shall not be attached to a service mast between a weatherhead or the end of the conduit and a coupling, where the coupling is located above the last point of securement to the building or other structure or is located above the building or other structure.
