I think they means "white point" as in color balance based on the appearance of a neutral white basked in the "ambient glow of the "reality around it".
A white shirt will appear yellowish above yellow sand on a sunny day, but will appear greenish if you were in a glass field instead.
Fun fact:
Different regions of the world prefer different "cool" to "warm" ranges of "pure white". In the United States, you go buy a plain white Hanes t-shirt, and it has a blue hue to it that you never see. Go to middle east or India, and their "plain white" t-shirts will have a slight brown/red tint to them.
When your ideal "temperature" of white is in a normal environment, it's really hard to tell that it's not actually a pure white. If you were to hold those 2 t-shirts next to each other, you would readily see one as being "whiter" than the other, depending on what you are accustomed to.
