There are definitely questions it that can discriminate this. Sometimes it will take a 2nd or 3rd question to be clear it's a distraction.
One example is a candidate that was talking about residential firefighting. I asked them about halon gas as a way to fight with quite a bit of curiosity, and they shut me down. I've learned to trust my insights, because I've seen them confirmed in other ways throughout the interview--it builds a pattern. When it doesn't fit the pattern, I am open minded that it's a fluke.
Ultimately, I think the "trick" nature of this is over emphasized by my blog. The single most telling factor is whether candidates can clearly explain something in essentialized form--that alone is difficult for most people.
