The helicity associated with the writhing number is obtained by observing that a torus with twist number ±1 may be distorted into a figure-8 configuration which appears untwisted.[…]Note that at each step the total helicity, consisting of the sum of twist, kink, and link helicities, is conserved.

Thus the total helicity H equals the sum of the entries in a matrix Hᵢⱼ. If N is large then there will be many more mutual helicity terms. In this case ignoring the self helicities (if they are difficult to observe) may only give a small error.

Now conservation of helicity is maintained: the writhe of the loops in the second panel is compensated for by the opposite sign of the twist helicity along the loops.
