1) Adolescents are well known to be more confused about sexuality than adults, often conflate friendship and charisma with sexual attraction, and often experiment with sexuality and later decide what's for them. It's not surprising at all that the number of bisexuals would drop.
2) As I read this, they changed the question from "romantic attraction" to "sexual attraction" between the two surveys. Seriously???
