I'm trying to learn this solo and I've got it all down pat but I'm struggling with this one part that looks like a small series of hammer-ons. Watching closely, it looks like he only picks the G string but it also looks like his middle finger hammers onto the D string? I also can't tell if his ring finger is doing or his pinky. Even at this speed, I can't figure it out.

Anyone able to decipher this one? Cheers!

Try to slow down the video and then try to observe it properly. Or else try to show a best guitarist near to home. They can understand by musics.
