I think you did misunderstand, what I took from his post was that either as Silca do you can use fine diamond particles to polish the internal surfaces or you can use dirt (probably not quite as abrasive) to polish. This process in engineering is called “bedding in” not imbedded. Once the surface has been polished with grit then you want to do is get rid of the grit so the deep clean is necessary to stop the grinding process. From there apply lube of choice and ride on.
Because wax will not allow the bedding in process to occur then you will not get the same surface prep. Do I care? not for 0.5 watts nope no way, just clean off factory lube, wax and ride. I believe @TomasIvarsson did a fairly good job of explaining the bedding in process and what a surface change looks like.
