Words in quotes aren't suggestions. They tell us (I work for Google Search) to find only what's in the quotes. That's how they've worked for years. We haven't been "only obeying them" if we agree. I'm not even sure what that's supposed to mean. We obey them as outlined in that post. The problem is that people sometimes can't find the quoted material on the page -- that we definitely did see and definitely did restrict to -- so we made it clearer in snippets to help them understand what we saw, where we saw it and hopefully guide them to the right locations in the doc.
