To be fair, they're talking about Kahneman's '79 research and then talking about how they build on top of that. I guess yours maybe could be modeled as the inverse planning fallacy - you hold over-pessimistic beliefs about the ease of the task. This happens to me too: e.g. when I don't call the bank to do something because I think I'm going to be on the phone for forever, and when I finally get around to doing it it really only takes 5. So perhaps the model could accommodate that, but I'll admit to having skimmed a bit and closed the page. I agree with your sentiment though!
