Why not use clearCookie() to remove express session?

I tried this without watching the video and it worked fine. 

res.clearCookie('connect.sid')
res.redirect('/')

It removed the cookie containing the session and the site went back to a logged out state. After watching the video and implementing the session.destroy method, I then saw the question had the clearcookie() option listed as a wrong answer.

based on the video, I came up with this:

if (req.session) {
  req.session.destroy((err) => {
    if (err) {
      next(err)
    } else {
      res.clearCookie('connect.sid')
      res.redirect('/')
    }
  })
}

It clears the cookie after logout as well as destroying the session. Is this OK or is it going to cause some unforeseen consequences?
