That cable is permitted for that application. There are a couple of listed cables of that construction. It is my understanding that those cables are based on 725.136(I)(1) with the control cable having a jacket that is listed as non-metallic sheathed. My friend Ryan Jackson agrees with with you that it is listed based on (I)(2). In either case it is a listed assembly that is permitted for the application.
As I recall this thread is based on a conduit installation, and other than re-classification, I am not aware of any method that will permit the Class 2 cable in the same raceway as the power conductors. If you could buy the same cable as Southwire has used in the cable you linked to, it would be my opinion that you could install that in a raceway with the power conductors, but as far as I know, you can't buy that product.
