Sasuke's first use of nature transformation was during the bell test, when he used Fire Release. Then, during his fight with Gaara in the Chunin Exams, when he uses Chidori for the first time, Kakashi says the reason he wanted to train Sasuke was because he was the "same type" as he was. Dunno what is the proper translation. Just because Sasuke used Fire Release first, it doesn't mean that's his affinity, it just means that's the one he was trained in first.
