Hello. I know this is a bit of an odd thread, but I guess it fits best here.
I'm new to piano so I'm wondering is this guy using a sustain peddle? I noticed the notes continue to play even after he's let go of the key. I tried to follow along, but because of this, it requires different finger placement.
Yes he is either using a sustain pedal or he has simply edited the sound to have a very long release time (so the sound continues long after releasing a key).
He uses very awkward left-hand fingering and technique. Don't copy this.
