Even if this is true, it need not be either-or. Saying that they are 'actually' autistic seems to imply that you do not believe that they are 'actually' trans.
For what it's worth, I didn't mean "actually" in an either-or sense, but more in an unexpected-correlation sense. I tend to avoid ontological discussions on this topic.
English is not my native language, I sometimes miss the subtleties.
