Why does everyone think concrete striping is from overlap?

I sometimes use what I call the "carpet cleaning method" which I think is basically whet he is talking about here. I do it on sidewalks so there is less moving the hose all around. I also do it on softer concrete so there is no etching lines nto the cream coat. It is slower and much more laborious but it works and doesn't leave lines or stripes.
