How to read 3-way differences in TortoiseMerge?

Hi,

When I do an SVN Update, I notice a few items that are "Merged" (green). I
right click these and go to "Compare with Working Copy" because I'm
interested in seeing *what was merged into what I already have*. However, I
end up getting horribly confused because it's not showing me anything
useful. I have no idea how to read the differences. What is it comparing
against?
