Puffing technique..?

[Revan33]

Hello all I am a non-smoker, I was wondering if anyone knows exactly what this guy is doing in this clip, he seems to inhale then rapidly puffs, removes the cigar and slowly exhales.. is it some kind of breathing method? I don't smoke so perhaps someone knows stuff that I don't or perhaps this guy just has a strange style, I'm trying to understand the logic behind his breathing/smoking.

Is that an e-cigar? And if not, how do I get the tip of my cigars to burn green?
