I was taught that the 2nd knot just provides quick visual proof that the tail is long enough to not pull through under load.

- tweetle_beetle 4y agoYes, exactly. It's a test rather than a functional feature. It's useful in a group context for visually checking safety. However, it can be less safe for shorter people and children, especially on a thick, worn rope - it can end up as a solid block which accelerates rapidly to face height during a fall.
