Nope, it's still soap, it just has added glycerine. If you make soap in the traditional way, by saponification of fats, there is always glycerine in the soap. Fat's are triglycerides, a combination of three fatty acids with glycerine. Soap is actually a salt, formed by the reaction between the fatty acids and the base (usually lye so its a sodium salt), for soap to form, the fatty acids must first be freed from the glycerine, this results in the formation of free glycerine. Unless this is removed from the mix, it remains with the soap. If you add glycerine, either during the initial saponification reaction, or during reprocessing, you will have added glycerine, but the actual soap remains the same.

Cold process soap also contains water. This is because you add the lye as a water solution. You can add water to the mix as well, but this does not change the soap, it just adds water. Glycerine, water, fragrences, colors, and extra fat (as in super fatted soaps) are all just additives, the soap is still just soap. You cannot make soap from glycerine any more than you can make it from water.
