I don't agree with this based on the specific example that she provided. Searching for legacy files, or annoying historical lessons, especially in a codebase you're entirely unfamiliar with, is a perfect example of a time to ask a question like that. In fact, I might even put it as an oversight of the engineer that's guiding the new engineer if they didn't tell their coworker where the files are, especially when there's been a shift between old and new styles. It's okay, though, experienced engineers make mistakes, as well.
