Three channels glass - Materials and Textures - Blender Artists

On the left side of the image,i have made a glass shader, adding three glass shaders with red,green and blue colors. On the right side there is the default glass shader. With 3 separeted channels ,in theory,adding the 3 shaders should be physically correct, but the result is two different images. Can anyone explain to me why?
