More than likely, it's just not well thought-out. That person drives on the roads, so of course they need to be cleared. He doesn't walk on the sidewalks, so of course using salt on them is a waste.
I'm not bothering with calling the city too much this season, honestly, but I personally loaded up on salt a few months' back and am dumping it liberally on my kids' route to school where I know that property owners will not clear. I've cleared a few windrows that I know never otherwise will be, but I'm not usually the one walking them to school and not usually able to take my shovel with me.
I've always tried to use salt pretty judiciously on my own sidewalk, and usually find that it's only infrequently. But I figure if I do wind up dumping 150 kilos of salt on other people's sidewalks this season, it's not even a rounding error compared to the thousands of tonnes the City uses making sure the roads are clear and dry.
