Wikipedia already has a full write up. It looks like Fable simply found an example of a function that had a constant Jacobian determinant (the determinant of the matrix of partial derivatives), but the function was not injective (3 different values of x, y, and z give the function the same value). Basically, the function is not "smooth", so it can't be inverted.
