this phenomenon is fundamentally about the mathematics of binary numbers, not the details of the representation as two's complement. mathematically, this is complementary to the fact that the negative of 0 is again 0. for a given number of bits "k" there is an even number of binary numbers 2, taking negatives is a group action (of the group of order 2) on binary numbers, and since the orbit of zero has order 1, at least one other number must have an orbit of order 1 for the orders of the orbits to add up to the order of the set. thus some other number must be invariant under taking negatives (formally, by the orbit-stabilizer theorem). geometrically, one can view the "k"-bit binary numbers as the cyclic group formula_3, which can be visualized as a circle (or properly a regular 2-gon), and taking negatives is a reflection, which fixes the elements of order dividing 2: 0 and the opposite point, or visually the zenith and nadir.
