Here is that thread, with some helpful insight from Ditte.
" "Remember me" is only for remembering the email, and nothing else. It doesn't keep the user logged in or auto log the user in. This is a shared feature of the entire login mechanism."
So, long story short, it's not supposed to auto-login, and InSided can't force that due to data security.
If you do experience a smooth auto login, it's most likely a browser feature or setting.
That said, it should be remembering just your e-mail address. If you would like for your password to be remembered, you may want to take a look at password vaults and other browser tools.
