He is allowed to add categories to your pages; however, the categories he added in this case do not seem to be necessary, and in either case, you can remove them if you so choose. I do recommend that if a category such as Bad Grammar is added, then you check to make sure the page is okay. Generally, these types of categories are only added when the problem is severe and not just one small mistake.
