No, this is actually not what it means. "Office hours" has two distinct meanings: one is the hours you are in the office. That is not what is meant here. The other meaning, which is what is meant here, is specifically designated times when experts make themselves available for random questions about the thing they're an expert on. For example, I work on a project that heavily depends on "library foo". The guy who wrote "library foo" (who is an employee of my company) holds "office hours" for one hour every Monday, where he commits to being in a Zoom call that other employees can join to discuss questions about "library foo". That does not mean he only works for one hour a week.
