"intensive" means that the value of these quantities at a given spatial location does not depend on any value of the neighboring intensive quantities. In contrast, "extensive" quantities depend in the intensive quantities of the environment of the spatial location. this change is necessary is because the previous nomenclature was very specific to finite volume discretizations, but the models themselves were already rather generic. (i.e., "volume variables" are the intensive quantities of finite volume methods and "flux variables" are the extensive ones.)
