Technique revelation on jibing and for bottom to top turn

Agreed we don't need that much leverage unless overpowered but what it does is that it places the body more centered across the sail. There's a better inherent balance which can lead to easier moves such as jibe variants. Also it's used for speed loops.

With a front hand back it also keeps the mast father away from us when bleeding off the power. Through an onshore bottom turn, it'll increase sail control as we go clew first.

I also think that leverage (good fulcrum) is not what we are looking for when putting the hand back. It mostly prevents sheeting out and also bring the sail forward to steer downwind. As Manuel said, you are also ready to sail clew first if required.
