Mike,

Guy's interpretation is correct. You are fine with air or argon in your suit.

With regard to the efficacy of argon as a drysuit inflation gas, the only study which examined the issue in a blinded and objective fashion (including thermistors on the skin surface and up the divers bums) found no subjective or objective benefit (tested vs air during drysuit diving in very cold water).

I would definitely not go to the bother of carrying an extra cylinder of non-respirable gas.
