That isn't a Hufflepuff torso, the H stands for Hogwarts. It's the uniform worn by the students before being sorted into school houses. The Harry minifigure in #4701 Sorting Hat (the right hand figure in your photo is the correct version from this set) and the Hermione figure in #4708 Hogwarts Express use this torso.
The head for the left hand photo comes from the Ron minifigure and the hair is from the Draco figure.
Unfortunately as the forum is hosted on a third party platform we are very limited in what we can change with suggestions like this. Hopefully these improvements will be included in a future update from Vanilla.
