Using Ultimate Facebook

I am trying to understand how Ultimate Facebook works.

It seems that there are some plugins whose events take place once you are logged into your WordPress site. I assume this, like Twitter Tools or others, is one of them. If you are logged into your WP site AND you are logged into your FB account, this plugin will work.

If you are not logged into your FB account, this plugin will prompt you to log into your FB account and then ask permission to be tied to your WP account.

Is this correct?
