This is something I didn't fully understand until I was hired into a position of a formal role model - principal engineer on a new team of fairly junior engineers. My manager had several conversations with me to drill into me that I now had to keep in mind the power of my example in behavior for the team. It's not that I was a bad role model, just that it wasn't always front-of-mind for me.

I think it's easy-ish to get promoted to Senior based on your personality and inclinations that lend themselves to being a "natural" role model; moderate deficiencies can easily be glossed over as long as there's enough compensatory strengths, and you aren't expected to be perfect. But once you start to become a role model - formal or informal - you gain a new job responsibility: consistently demonstrate the culture of professionalism and courtesy the company wishes to inculcate. Because your actions will be emulated, for better or worse.
