I'm also not sure what this is referring to. The pedestrian line is already marked as "footway=crossing", implying that it's in a roadway. The residential area is already set back from the pedestrian line. The reason the line seems to be "within" the block is just due to the width that OSM automatically renders road lines. I don't know if adding road widths will change the way that they get rendered?
