There are wrong descriptions of two methods in section 6.2.7. in User Guide.

My suggestion: Switch contents of these methods:

When you set skin using method one change is applied to this portal, and every user that accesses this portal will see it in the chosen skin.

When you change skin using method two, the skin is set for the logged in user and all portals within the domain will be shown with the chosen skin.

Method One
1. Click on Site, then Edit Portal's Properties.
2. In the Portal Setting tab, select another skin Skin list 
[...]

Method Two
1. Mouse over the Start menu and click on Change Skin. 
[...]

Another suggestion: 
Add "Skin changed by method two has higher priority." after "When you change skin using method two, the skin is set for the logged in user and all portals within the domain will be shown with the chosen skin."
