From "man emerge": --deep (-D)
When used in conjunction with --update, this flag forces emerge to consider the entire dependency tree of packages, instead of checking only the immediate dependencies of the packages. As an example, this catches updates in libraries that are not directly listed in the dependencies of a package.
To sum up, portage will look for updates not only in your world file, but on dependencies too.
