He sees a reflection of what he looks like (flipped, as images in
mirrors are).  If he knows about mirrors, he knows that what he sees
in the mirror isn't even a P-zombie, but just a reflection.  Likewise,
if he saw the reflection of a (known to him) P-zombie, that reflection
wouldn't be a different P-zombie, but just a reflection.
