Your edit is good. The Visual Editor sometimes adds the unnecessary codes that we don't need (it won't damage page but just may increase little difficulty for people who're preferring to edit in source.

It's reported that Visual Editor sometimes can cause glitch such as category is gone, content of page is lost and such and that's why we should avoid the edit in visual. Beside visual don't support editing advanced codes.
