You are correct, but somewhat missing the point. Once you can measure "love" and categorize different variations of it in an objective manner, you can start studying causality and a ton of other interesting features of the phenomenon. It creates a real-world scientific metric for studying "love" in all its dimensions, including cases where "love" creates pathological conditions.
Otherwise, discussions of such things reduce to arguments of semantics, lacking objective definitions and metrics of such things. A good example of the problems caused by only having semantics is the usage of terms such as "rape", which the feminazis throw around willy-nilly. Establishing definitions and metrics that are decoupled from the semantics and emotional baggage force discussions to be rigorous and rational in ways that would be impossible otherwise. This is a good thing in my opinion, because it allows us to decisively refute some of the fuzzyheaded arguments from the leftists, feminazis, and similar. Emotional arguments are the last bastion of left-wing morons; if we take that away from them, they have nothing left.
