That's pretty much what I'm arguing.
He was near the sideline after a change of possession and he was walking down the field to the bench.
Although the letter of the law is "don't take your helmet off, ever", guys do take their helmets off on the way to the sideline (even when it's not change of possession) and no penalty is called. I think in the last game, Barwin even took his helmet off between plays (I think he was examining the inside of it) and they didn't call him.
