I don't see a problem. Some different emphasis of principles is used in forms. That's actually pretty common in my experience - it's sort of the basis of the classical Japanese MA training approach, IMO. That doesn't eliminate the two really odd issues with your claims here: Just because a punch is identified separately (with additional principles) doesn't make it suddenly not within the category of attacks. Just because something is done differently in forms, that doesn't mean the same principles don't apply (they often are applied with different emphasis). Keep training and learning.
