BP Social Child Update 1.2.7 - Used automatic update for main theme

I have a question, which shows some of lack of complete understanding around the whole parent and child theme. I am using social, and I recently updated everything, plugins and all, to BuddyPress 1.5. This was surprisingly smooth, but I have the luxury of it being on a new site that isn't live and hasn't had a lot of customization yet.

My question is probably easy, but for me not clear. I updated the Social Theme to 1.2.9, but I still see the child them as 1.2.7. Do I now have to go download that Social theme, take out the child theme and upload it? Or is there a way to automatically do it? Or did the automatic updates take care of everything that needed to be?

Thanks, David
