Hmm, a clear history feature that does nothing of the sort. Sounds like Facebook!
The product manager in charge said: “people were able to mentally connect that with how their browser controls work, where they can clear their history. We clearly state that … the information isn’t connected to your account.” [0]
So, they deliberately designed it to make people think it works like a browser's clear history feature (which does delete everything), but instead, it 'disconnects' the data (but doesn't delete anything).
