Well for one "emerge -e" will pull in build-time dependencies which "emerge -u" won't (unless it's necessary for an upgrade). So hypothetically let's say you have firefox in your world file, and you have the latest so "emerge -u @world" doesn't pick it up, but say you "emerge -e @world" and firefox needs "=automake-1.6.*" to build, but you don't have that version anymore because, say --depclean or something else cleared it out or you have automake-1.6.1 installed but it's no longer in portage but 1.6.3 is, then automake-1.6.3 might show up as New or Upgrade or even Downgrade (since it's slotted). -a
