The article doesn't say "immediately", and false confessions do occur, unfortunately. I hope you're right, that it's just one tool to help direct an investigation, and that the confession was true, but I'm not entirely convinced by this article. It starts by claiming he can tell "whether the knot-tier was left- or right handed, skilled or novice at knot tying, and in some cases, whether the crime was premeditated", but only a couple specific stories are given, and one was a knot which "people wouldn’t know of outside of the butcher trade", which is much more obvious and grounded than the earlier claims. Of the first 14 Google Image results for "square knot" (before it starts returning other things), 8 tie it one way, and 6 tie it the other way -- and as I scroll down, this ratio seems pretty consistent. He claims for a right-handed person "the knot will almost certainly be formed right handed", but at first glance it seems much closer to 50/50.
