Simple answer, no he can't.
Got a reference for that ? Just because it's common sense, doesn't mean that it's correct.
The general case question would be "Can someone who is authorised to conduct flight reviews (defined in the regs as 'an appropriate person') conduct their own flight review ?" I don't know of anything in the aviation act, regs, orders, aip, etc that would prohibit this, either explicitly or implicitly.
