Pretty sure she's not. If you hover over the icon on her profile picture, it says "Expert - Google Products". I can't find an example, but as I recall they have something like "Google Employee" that leaves it in no doubt when it's an employee response.
I've never seen that, but maybe I've never seen an answer by an actual google employee. :/
getting even a canned response like that is luxury, when it came to google's support.
