It entirely matters if Mashima does or doesn't explain them. If it is not explained why Acnologia could not detect that she was not a dragon, even though it has been confirmed that she merely was given her human shape, I will have issues. You shouldn't have to assume stuff to get rid of plotholes. They just shouldn't exist.
