And? You still wrote an incorrect assertion..
*Using* internally a RISC or *being* a RISC i.e having an externally accessible ISA which is "reduced" are different things, whether it is relevant to your discussion or not I don't care.

RISC design principles are about more than just how many instructions there are and what they look like, even though you can argue that most RISC CPUs drifted away from those principles pretty quickly. One can argue that x86 instructions translated to "RISC instructions" does resemble x86 instructions being implemented by microcode, but I imagine that refactoring the microcode and working out a better set of directly implemented instructions is very much taking the RISC approach, even if all this is hidden by the x86 layer in the final design.
