No. See my other reply above. You're ignoring important context that defines personal behavior separately from defining what the professional duties of an engineer include. As a simple example, if you have a faint and I ask you if you're all right, what you're feeling etc., that doesn't mean I'm practicing medicine without a license despite the diagnostic nature of my questions.
I'm saying the Board's justification clearly says, irrespective of whether he said he was an engineer, just engaging in the practice of [creative work using mathematics and engineering knowledge] is subject to registration. I mean, if he hadn't said he was an engineer to Licensed Engineers many times, I agree nobody would have bothered. But now that they've bothered, their justifications matter.
