Even if the conscious states in humans are more intense, it doesn’t follow necessarily that consciousness makes them more intense. Probably some of these people would respond to you as follows more intense states have more influence in the brain, and so in humans they are more likely to attract the attention of introspective mechanisms and become conscious in particular, but in animals without introspection, having more influence does not mean being conscious, because there is no introspective mechanism to attract the attention of. (I am improvising here somewhat, I’ve never seent his combination of views specifically.)
