They've probably changed the way they do things. When Sayu, Reina, Gaki, and Ai-chan graduated they had long tenures and thus got solo songs. When Riho, Zukki, and Duu graduated they got A-sides where they were the center. Now that Haachin's graduated, Morning Musume has gone back to doing Double A-sides again, and moreover I think H!P is starting this new "bonus track" thing with songs like Hello! History, so they probably decided to make Harunan's graduation song a "bonus track" to sort of implement this new "bonus track" system.

And, hey Tanaka Reina's graduation song was a b-side, and she has the third longest tenure in Morning Musume.
