If anything, I find this to be a, perhaps unintentional, damning indictment of psychology and psychiatry in general.
If your discipline cannot clearly define things in a reasonably concrete and provable way, such that it is readily apparent to the patients and the public at large, and also such that the language effectively clarifies itself out of necessity, then much of what you do needs to be strongly questioned -- and often not taken too seriously.
I'm reminded of e.g. the term "neurodivergent." It's a good thing to look at, but how do you falsify it? Who can stand up and say "I'm definitely not neurodivergent?" If you can't do that, the term is not very helpful.
