And if/when the feature launches I would not at all be surprised to seeing this headline down the road:

"Facebook Clear History doesn't fully erase user data, information later sold to a group of Zombie Nazis bent on world domination."

And it is mentioned as such in the article too that "Clear History =/= Delete History"

> There’s a reason that Clear History isn’t called “Delete History”: Using the feature will disassociate browsing data that Facebook collects from your specific account but it won’t be erased from Facebook’s servers completely, Baser said. Instead it’s just “de-identified,” which means it’s stored by Facebook but no longer tied to the user who created it.

At Facebook's granularity of data collection it would be almost trivial to identify a user even if that user's name is not connected with the data.
