He's good, but I wouldn't say that's anything spectacular. We call the type of tip a "mini-wave". It has a concave side (that isn't shown in the video that I noticed).

A bit of practise and it's fairly easy to do. He doesn't really explain anything though.

1) Tack down the IC using the corner pins.
2) Apply some flux.
3) Use that technique.

I've never done it "vertically" but it works quite OK for me horizontally and I doubt it would make that much difference to be honest.
