Well, I said that in the above paragraph of your quote - probably less absolute force is occuring through the body which makes the CNS accept it much easier, without the fear of things breaking up, and allowing a faster coupling phase etc, and the tendons pretty much maintain their material qualities regardless of weight, so the structural factors that have nothing to do with muscular strength, like Avishek used to say "muscles don't have anything to do with this bullshit" - these structural factors start playing a more important role at a lower bodyweight. Otherwise the CNS is going to make you use less speed in the plant to protect them, speed that has to be compensated for with voluntary power.
Since both athletes have the same voluntary power, then the heavier athlete will jump lower, due to the loss of speed in the plant/loss of accumulated momentum which would otherwise add to the voluntary power that is identical.
