I'd wager it can't teach you abstract concepts but since abstract concepts are much easier to learn with the practical knowledge of using them, it would definitely be helpful. Also honing motoric skills is a key part in doing many things - arts, sports - so getting accustomed to that is a big plus too. The downside of doing only that is yes, you will be quite lost with the abstract and also reinforce some bad habits. So no cynical HN commentary from me! If it works, it is definitely a big help for learning to play piano.
