It's taught that if you turn your head before the ball arrives, it's not pass interference.
Unless you're these refs, in which case you could even run backwards the whole time and still get flagged.
I know you don't like the Chiefs, but that was textbook defensive pass interference. Turning around to make a play on the ball is completely irrelevant when you mug the receiver way before the ball even gets there.
