It's just an alternate method to get back your account if passwords ever become an issue it comes in handy sometimes.
No it doesn't especially after the 2015 hack. So I still don't understand why the option is still there
Even if you guessed it correctly your account is still locked
And many people are not really aware of this feature.

This is a Public Service Announcement:

If you lose your password, DO NOT USE THE SECRET QUESTION TO RECOVER THE ACCOUNT. It will result in your account being locked. Please use the email recovery option to recover the account.
The reason that the accounts are locked is because the May 2015 hack leaked Bitcointalk's database which did not securely secure the Secret Question and Answer. To prevent people from guessing the answers
As was Announced by Achow, It doesn't really change anything.
