The idea behind doing the upgrade in 2 operations and doing "pacman
-Sywu" in the GUI is that it allows you to continue working in the GUI
while the packages are being downloaded. So you don't waste time in
the console waiting for pacman  to  download the packages.  Of course,
if you are not using the GUI or don't mind waiting, then you can just
run "pacman -Syu" in the console.
