A quick look at apprndix B (page 357) defining a circuit. To me, this seems to say that this is still just one circuit, this gives some validation to rule 14-010 (b) for which a single multipole switch should have been installed. I guess it all may depend on the weight each section of the code has on each particular topic. Perhaps this is one situation that would need clarification by the inspection branch...any inspectors out there???
