What do we call a way of differentiating objects within the same feature class?

Differentiating objects within the same feature class is done by assigning each feature a category value from a predefined list. That predefined list is an enumeration—a defined set of distinct values that describe the possible types or subcategories of features. Using an enumerated attribute makes it clear and consistent how features differ, even when their geometry is the same. Other options don’t fit as well: emulation means imitating something else, and an explanation isn’t about categorizing data. Type coding is related but the standard term for a fixed, finite list of categories is enumeration, which is why it’s the best choice.
