The quote didn't say "fabricating", it said "not entirely true." The way you're interpreting the quote, it would be ludicrous, I can agree. The way it was actually written, along with what I interpret to be the broader point, I think the article is somewhat true, and has a valuable message.
STAR and SOARA are a way for the interviewer to drive the requests for information, force a conversation, try to frame the question so that candidates can be more easily compared, and prevent the candidate from rambling and offering irrelevant information. The article's suggestion has the same goal, aside from the truth detection part, which I'm downplaying here.
Don't focus on a single quote and ignore the article's larger context. The author also said "If you get too far into a story without making sure they are still with you, it comes off to the interviewer that you cannot explain things well." and "If it’s not obvious yet, force the interview to be a conversation." All of the sections lead to "force conversation", if you can get past the part about speaking backwards being more truthful.
Conversations almost always run backwards, in portions. Anytime you answer a "why?" question for example, you're telling the first part last. I suspect that's what the author was trying to say, less that narratives should always be presented backwards, and more that conversations are desirable and conversations often run backward.
