I just checked the pitches. The music started out in G-sharp, but from the start, she heard it the way she rehearsed it, in F natural.
Those two keys are a minor third apart, and in entirely different families. They clash horribly together! But she's a solid singer and stayed within F natural, which would make the highest notes much easier to reach.
She may have had a recording of it performed in F natural, and practice to that a thousand times. Once you've done that, your vocal chords just know how tight to be.
