Really? Where? I just reread it with that in mind and I still couldn't find it. The closest I came was that he once used the term "sentient simulation", which is at least technically broad enough to cover both. He does make a point there about sentience being something which may not exactly match our concept of a human, is that what you're referring to? He then goes on to talk about this concept (or, specifically, the method needed to avoid it) as a "nonperson predicate", again suggesting that what's important is whether it's like a human-like rather than anything more fundamental. I don't see how you could think "nonperson predicate" is covering both human and nonhuman intelligence equally.
