I think Picasa didn't even match all the photos of my cousin from a single vantage point within 20 minutes of each other. The software is good, but it isn't superhuman.
I'd imagine what is done is that a set of faces are recognized automatically as being the same and one image "idea" is stored for that face, another set of the same person that are slightly different are recognized and a second image "idea" is stored for this "new" face. Now when you tell the program that both of those faces have the same name, future photos will be compared to every face "idea", and no matter which "idea" associated with that name is picked as a match it will still link back to the shared name.
So if you import all of your child's pictures from birth to college, it will, with your help, know a large variety of faces for that child. Each of us is unique though, so even though it may know 50 faces for your child's first twenty years, it will not confuse those with the billions of other possible faces.
I am pumped for this cool new feature... and desperately waiting because I almost ordered a new MacBook Pro on Monday but now want to make sure it will ship with the new iLife. No sense in paying $10 for it at this point.
