i never got it either but then i realized its smth ppl do to make themselves feel better abt their decisions & reduce cognitive dissonance. theyre feeling a sense of rejection & discomfort (i wanted them, why didnt they want me) so to boost themselves up, they lower their ex down & tell themselves "actually i didnt even like them all that much in the first place, they were *insert bad trait here* so its fine that they rejected me"
