A useful knot, although I think you may mean "temporary" ("not lasting long").

Yes, you are right. It should say temporary, meaning a knot that will serve its purpose for just as long as you are working on it. My English is not so good. The Instructable came out a bit too dry, I should babble more. one day i will learn. thank you, tekaka
