He is not correct, the insulated conductor is not necessary but a sheath that is recognized as an EGC per 250.118 is, see exception No 2 to 517.13(B)

The inspectors advice is commonplace here and, as Roger notes, it is not an accurate reply.
In that the "green MC" (HCF Cable) meets the requirements he notes and it is most likely already at use on the job, inspectors often "shortcut" and simply state "use that cable" rather than go into an explanation
