session()->stop() not destroying data

I may be doing something wrong but I am calling the above

PHP Code:

session()->stop(); 


using the database driver but the session still lives?

Watching in the background, the session cookie does indeed get changed to a new id and the database table is updated with this new session id (and the old row removed / updated) but it is like all the session data is copied across?

Is this a bug or am I being a doughnut...

Thanks
