the weight of the tines are balanced by the handles of the fork which extend to the other side of the contact point between cup and toothpick

counterbalance provided by toothpick on nonfork side is negligable, therefore has no effect on the structure when removed

as long as the center of gravity remains over the edge of the cup, the structure is stable

Good one!
