No, that doesn't fill your needs. The ability to fill in 'extra' fields on the Registration page is something we're shooting to have in the 3.2 release later this month. The feature that mentions is that a user's status from Facebook can be pulled into JomSocial as the user's most recent status on your site.
We're working on a backend demo (as well as some other promo things) for JFBConnect, but simply haven't had the time to finalize everything we want to lately while we keep adding great new features.
Definitely keep an eye on the changelog, our blog, and/or our Twitter account. When 3.2 comes out, we'll be shouting about it from the rooftops
