Also i find it weird, because she has hit high notes with a nice natural sounding vibrato in not-so-far past, and did a good job in the LINE LIVE too.
I might ask one of my friends about this who actually IS learning vocals from a legit source lol i'm curious now, and i know too little about this stuff myself.

I mean if you use vibrato it's much easier to hold the note. If you aren't a highly trained singer and you're trying to hold a note without vibrato, you will strain your voice and won't be able to sustain tone. Not stating that her vibrato is proper, just that without any vibrato she'll be in trouble.
