That's part of the question, and I don't claim to know the answer: if the first link matters, is that the first link in the source code or the first link that can be seen on the page? In my tests, the first link has met both of those criteria, so while I don't have to worry about whether what I'm calling the first link is what a search engine would consider the first link, it does mean that I can't say which of the two (if they were different) a search engine would consider the first. If I had to guess, I'd say it's the first one in the code, but that really is just a guess.
