If new headers show up on the server, it downloads them.
When running something like "yum update" or "yum list updates", however, 
it is only looking for new versions of packages that you actually have 
installed.

Basically that means that some packages that you do not have installed 
were updated. "yum list available" will list available packages that you 
don't have installed.
