1. it might be old stuff that really isn't needed anymore, as already 
mentioned by others

2. portage up to a short while ago had a bug (or feature?!?) that when 
you emerged a package for the first time and used -u to do this, it 
would not be added to the world file. Nowadays it does the right thing 
and adds it to the world file if you use -u or not. This means that 
possibly some packages that you emerged yourself and weren't pulled in 
as dependencies by other packages in the world file are now regarded by 
--depclean as unnecessary, as they don't appear in the world file 
themselves and aren't dependencies of anything in there.

This means that you'll have to go through the list resulting from a 
'--depclean -p' and have to see if you truly wanted that package, and if 
yes, re-emerge that package or add it to the world file yourself.

Once you're done remerging the stuff you want to keep and have cleaned 
out the rest, it would probably be best to check that everything is ok 
with a revdep-rebuild

In the future though, everything should work fine just as you were doing it.
