The browser has a cookie with an ID that corresponds to a row in the 
sessions table, which is where $bar is stored.

If the user has the browser set to erase cookies when the browser 
closes, then the answer to your question is yes, because Drupal 
cannot associate the row without the ID stored in the cookie. Else no.
