It probably is not a problem for anyone as your "max ability" is of course something you have access to. It's just better to have the steps in the wand than to let them rely on the person's own innate ability in "raw" form. 

Maybe the guiding spirit has such control of their power level that they didn't consider this part. It becomes an issue when you share things "out here" because other people don't function exactly like yourself, so anything shared should be a more toned down/diluted "mainstream" version.
