Scenarios in the article may be cherry picked and videos are not the same as being in the same situation in real life. Also in article they didn't have a chance to provoke subject into verbal contradictions as they were only looking at visual cues.

Even in the article they mentioned 85% success rate after some training.

I don't quite understand what point you're making. The article explicitly says that "spotting" a liar, that is detecting lies based on non-verbal clues does not work. However, other interrogation techniques, such as getting the subject to talk more freely to give them chance to make contradictive statements does work. That's what the 85% rate is about, don't use nonverbal cues, use verbal techniques.
