I'm the author of the article and the intensity is referring to the level of the light source used in the study to generate the data. See the study explained here: https://medium.com/hipster-color-science/a-beginners-guide-t...

but you're right, the intensity needed of each R, G, and B light sources to produce the correct color is directly related to how our eyes perceive each of those sources, so yes you are correct
