Indeed. The n modifier is overloaded, and its original meaning is 'non-jumping', only meaningful on a distant leap. With nn a backward-compatible convention for indicating it generated e.p. rights on the square it can be blocked. On a rider with distant leaps it should mean the individual steps do not jump. (Riders never jump over occupied squares in their path.)
Only on sliders it cannot be used in this meaning, and in that case it means e.p. capturable on the squares it passed through.
