You should. If I start calling myself an engineer, and start making noise, about how some bridge or other needs to be retrofitted right this minute... My opinion on the matter is not as valid as that of an actual engineer. And you should probably not conclude that the bridge needs retorfitting, solely on my testimony.

It's like a product manager, with no understanding of how software is built, coming to your daily standup, and telling everyone about what compiler flags they should be using. All the while, calling themselves a programmer/software engineer. If your company isn't insane, it should censure him for that - especially if he said he'll stop doing it.
