Android has a feature where you can indicate that contacts from disparate services are actually the same person. For example, I have my friend Chris in my Android directory, my Gmail directory, on Facebook and on Twitter. Within my contact list, I am able to specify that these are actually all the same person. They're still separate contacts from each service though, they're just grouped together in my phone's directory. I suspect that the problem being described happens when the only source of someone's email address was the Facebook contact, as I doubt that, e.g., a Facebook contact would overwrite someone Gmail contacts. At this point it's not clear, however.
