Yeah, Kittah's attachment shows the proper way to construct sand paths. In Graal, the sand path is usually used to show wear, where person(s) have taken a particular route, and over time the grass has started to die, leaving only dirt. In your levels, it would have to mean the person(s) have walked around a large area rather than a small path, which doesn't make that much sense.
