Don't change ANYTHING. That might work, but it can be a bad idea in some circumstances.
All you need to do, is let it reboot, when it boots from CD again, the first(and default) options is "Boot from HD" which you should let it do. Then it will fire up YAST again asking for the next cd, then the next, etc etc... Once all 5 are done is user creation.
If you go DVD or network install, it is all done at once. Then user and other configuration.
