What if only the bottom right border has a radius? In that case, there 
would be no problem. Same thing if the bottom right had a radius of 30 
and the top right had a radius of 20.

I agree clarification is needed (assuming you're right that it's not 
there, I didn't check), but I think it should just be that if the 
border-radiuses overlap, they should be clipped at their intersection.
