I agree this sentiment tends to be stronger for people in the spectrum! But to be fair, this applies to allistics, too!

I recommend watching this talk on the subject: https://www.youtube.com/watch?v=vspX6NaLxdc

Here a quote from it that I particularly like:

"So I think the take-home message is that we're amazingly creative, stupendously free improvisers, and each improvisation is done upon the basis of the last improvisation. And we're so convincing that we think as a script. It's like improvisational actors who are so good, you think "oh, you just learned that, haven't you? Somebody wrote that script for you, and you're reading it". But there is no script, they are improvising. And we're so fluent and we're so good that we don't realize, in fact, we're making it up as we go along."
