It is true only when only one child-node is true and the rest are false. The XOR uses a fuzzy algorithm to determine how true it is when there is missing data or levels of trueness.

The two child-nodes define the x and y coordinates of the point on the fuzzy curve. The leftmost child-node defines the x position while the rightmost child-node defines the y position (the trueness level for the given x value).
