If you tie an alpine butterfly somewhere in the rope, and then pass the other end through it, you can achieve a 2:1 pulley system in the rope. This greatly increases the compression of the lashing. Hard to explain, but you're basically using a fixed loop in the line as a pulley to increase the force applied.
