Yudkowsky was not fooled. He made three tweets on this subject in that time frame, which can all be seen using this link:

First tweet:

> ...can we get confirmation on this being real?

https://nitter.net/ESYudkowsky/status/1664313290317795330#m

Second tweet, which is a reply:

> Good they tested in sim, bad they didn't see it coming given how much the entire alignment field plus the previous fifty years of SF were warning in advance about this exact case

Third tweet:

> Disconfirmed.

https://nitter.net/ESYudkowsky/status/1664639807002214401#m

The second tweet does not explicitly say "conditional on this turning out to be real", but given that the immediately preceding tweet was expressing doubt, it is implicit from the context that that is what he meant.
