From that page, that could be a suggestion made while Siri Suggestions was on staying around after it was switched off as a ‘cached’ response. I also think that’s a likely explanation. If so, it’s a small bug (depending on how it’s phrased in the UI, one could even argue it’s not a bug because “I don’t want advise from Siri anymore” doesn’t imply “destroy all previous advise from Siri”)
