Please note that there's a not in the last part which denotes a current directory and as the result, a new directory (x86 or x86_64) will be made on the current directory where you execute this command which consists of all packages of KDE SC 4.4.4
When you are finished with the rsync, you can upgrade all the packages using
upgradepkg --reinstall --install-new x86/kde/*.t?z
upgradepkg --reinstall --install-new x86_64/kde/*.t?z
