It seemed to be a rather empty argument to me, too. When you're dealing with facts about the state of reality right now, "possible" is irrelevant. Something exists, or is true, if and only if it's possible that it exists / is true. Possible is only relevant with regard to future events.
He just seemed to be saying that if something isn't internally inconsistent then we can't rule it out; or that if something hasn't been shown to be impossible, then... it can't be discounted as possible. That just sounds like a pointless tautology to me. I don't see how we can learn anything through that. A "square circle" is an abstract concept anyway, and one we say is impossible by our definitions. We also haven't learnt anything about reality by noting that. What we're really saying there is that something we identify as a circle, we wouldn't also identify as a square. But even then, that depends on the geometry we're using. In topology, they are the same.
