When you put a conditional statement, new information overrides pre-existing knowledge. Otherwise, we wouldn't be able to do any theory what-so-ever, because "Well that's not like that in the real world!"
Just a random example: Imagine I ask you "Can you turn a sphere inside out, if you remove all physical laws and stay in a purely abstract mathematical world? ", it would be just wrong to reply "Well, physical laws exist, so no you can't".
That's stupid, especially when he instructs them to count the tail as a leg.
Critical thinking skills also include things like calling people out on bullshit.
