From your comment on this other post and the downvotes it generated on said post, while this post and your comment get upvoted, I guess neither you nor anybody even checked to see what "offline" means...
If you scrolled down a little from the link you provided, you would have seen that "offline" really means:
- Do NOT show the "opt-in" dialog to the user.
- Silently opt-in user to "suggestions"
So basically "offline" = "opt-out" and not opt-in.
