Please read about the history of Karate. Pinan Nidan IS in fact the original name of this kata. Later on, the Pinans were renamed as Heians and the order of the first two kata was switched. So depending in on style, this may be called Pinan Nidan, Pinan Shodan, or Heian Shodan. This style obviously retains the original name.
