That is sufficient, but I personally still found it intuitively unsatisfying why the configuration let me pull with less force until I realized the same force-lightening effect is already present in a simple half-connected hammock setup.
The hammock example is not illuminating, because it is wrong—you will often need more force in the hammock setup, because the rope is diagonal, not vertical.
I think it’s better to deeply understand the two principles I mentioned above (both just special consequences of Newton’s laws), because it would make the hammock situation more clear.

If the hammock has a narrow V shape then you actually will just need pretty close to 50kg of force instead of 100kg.
