If I had to guess, it's because Rebecca Shoichet isn't listed in the credits as singing for Twilight, and if you listen carefully to the section where the other five sing at Fluttershy, you can hear how there's no Twilight voice (coming from either Tara or Rebecca), though I haven't seen this episode in months, so my memory may be fuzzy.
