He really did. There's a little pause after that one high note in the song and especially when he's performing it acoustically, people often cheer after it.
Like here:
He's doing a Q&A here so the song starts @ 3:10 and the cheering is @ 6:05. (The Q&A part is kinda like an interview if you wanna watch it. xD)
I like this performance a lot too, I feel like it's actually more dynamic than the one above.
