No, you are the one providing misinformation. The explanation you linked to is completely wrong. "offline" actually means that you are silently and automatically "opted-in", so basically what everybody except Mozilla calls opt-out.
However, this does not change anything to the fact that these "suggestions" were silently enabled in Firefox 92, and that the opt-in dialog box was introduced only in Firefox 93. In addition, this opt-in dialog is not shown if you left your locale as the default "en-US" ("offline" = opt-out).
