Warning: I am not a CC rep. I'm just another guy who has posted several 
questions on the CC mailing list.


The point is that it's not hard to figure out which licenses can be 
combined with which. For example, a BY license can be combined with a 
BY-NC work, and the result can be BY-NC or BY-NC-SA, or BY-NC-ND. But it 
can't be BY. This concept is pretty easy to grasp. You can add 
restrictions, unless there is an SA in the license. You can not remove 
restrictions.
