It does illustrate the extra thread engagement.
Interesting that the counterbore in the new nut is 1mm deeper than the old nut. Made me wonder if with unfavourable build up of tolerances you could get a situation with the old nut where it tightened on the end of the shaft splines rather than on the sprocket. Same would happen if an aftermarket sprocket was a bit thinner than original. Maybe I overthink these things.
