It looks like false logic to me too, but I'm very aware that that is how many Christians "prove" their religion to be true. 'The Bible says this historical/Godly event happened and this archeological evidence supports the account in the Bible, therefore the Bible must be true about everything so God exists and I'm going to Heaven.' Which sounds very similar to 'This is a part of what you say about your religion and it may be proved false one day, so your religion might be too.'
Is it okay to slip into the streams of thought that the other considers logic in order to beat them at it and potentially shake their beliefs?

Basically, the question here is whether you can use the Dark Arts with purely Light intentions. In the ideal case, I have to say "of course you can". Assuming that you know a method which you believe is more likely to cause your partner to gain true beliefs rather than false ones, you can use that method even if it involves techniques that are frowned upon in rationalist circles. However, in the real wor...
You can have some fun with people whose anticipations get out of sync with what they believe they believe.
I was once at a dinner party, trying to explain to a man what I did for a living, when he said: "I don't believe Artificial Intelligence is possible because only God can make a soul."
At this point I must have been divinely inspired, because I instantly responded: "You mean if I can make an Artificial Intelligence, it proves your religion is false?"
He said, "What?"
I said, "Well, if your religion predicts that I can't possibly make an Artificial Intelligence, then, if I make an Artificial Intelligence, it means your religion is false. Either your religion allows that it might be possible for me to build an AI; or, if I build an AI, that disproves your religion."
There was a pause, as the one realized he had just made his hypothesis vulnerable to falsification, and then he said, "Well, I didn't mean that you couldn't make an intelligence, just that it couldn't be emotional in the same way we are."
I said, "So if I make an Artificial Intelligence that, without being deliberately preprogrammed with any sort of script, starts talking about an emotional life that sounds like ours, that means your religion is wrong."
He said, "Well, um, I guess we may have to agree to disagree on this."
I said: "No, we can't, actually. There's a theorem of rationality called Aumann's Agreement Theorem which shows that no two rationalists can agree to disagree. If two people disagree with each other, at least one of them must be doing something wrong."
We went back and forth on this briefly. Finally, he said, "Well, I guess I was really trying to say that I don't think you can make something eternal."
I said, "Well, I don't think so either! I'm glad we were able to reach agreement on this, as Aumann's Agreement Theorem requires." I stretched out my hand, and he shook it, and then he wandered away.
A woman who had stood nearby, listening to the conversation, said to me gravely, "That was beautiful."
"Thank you very much," I said.
