Unfortunately, there is no "turned out to be autism", just as there is no "turned out to be BPD". We don't have affirmative biomedical tests for these conditions. Until we do, they are just constellations - funny imagined shapes - that we're drawing in a galaxy of traits on display in that person's life. Your picture of a "tree" overlaps about 30% with my picture of a "mushroom". But it's not the case that "First it was identified as a tree but later turned out to be a mushroom". We pretend that these things are distinct biomedical disorders because it makes it easier to talk about them, easier not to literally murder the person displaying them, and (bizarrely) because it's legally required to classify them in order to bill a therapist/psychiatrist for their treatment, but in reality they're parts of a maladaptive personality that just look very roughly similar to other maladaptive personalities we've seen in the past.
