It's not clear from the article (which I largely agree with), but that "ability to change the decision" can just as easily refer to change the decision before it is made, instead of any ability to change it afterwards.

Amazon's concept of "two way and one way doors" is useful here. A two way door decision lets you go back if the decision turns out to be bad and can be made with significantly less scrutiny that a one way door decision which you cannot back out of after you've acted on it.
