Don't think too hard about the exact numbers would be my advice. In the model's complex view of the world, the high cloud may be in the same place as the low cloud therefore it doesn't add anything to the total cloud cover.

If the model sees the high cloud in only the places where the low cloud is not, then the two figures might add together. But in general that will not be the case.
