"Khaki" does not have a larger meaning than chino, it has multiple meanings, one of which is virtually identical to chino and one of which is entirely unrelated to that previous use of the word. The graph you use would be applicable to something like square and rectangle- all squares fall within the definition of rectangle, but the definition of rectangle encompasses more than just squares. In this case, we're not talking about one definition that encompasses a subcategory, we're talking about two entirely different definitions, one of which is virtually identical to another term and one of which is unrelated.
