Hi,
The site also has this information: "each calendar year, you have the opportunity to earn the certification and to receive an
additional entry on your transcript. You do this by passing a unique exam from the list of electives, which demonstrates your continued investment to broaden or deepen your skills in a specific technology area."
So this looks likes a poor choice of words that MS used, this will continue next year and an exam you passed this year will
still be valid next year.
