Interestingly enough, StrongARM was one of the few (and the first?) independent designs; it used the ARM architecture specification but not the actual logic design as others did.

Remember that the marketing in question was DEC marketing, well known for its utter ineptitude. That had its origin in Ken Olsen's belief that marketing wasn't really needed (and, for that matter, that sales people didn't need to be paid commission).
I very definitely remember discussions at the time about the unprecedented power/bandwidth value delivered by the SA110. "One mW per MIPS" is one phrase that I remember from that time.
