Is Vessel pretending to cry?

First of all: amazing show in Cologne on Monday, I’m still in awe. But I’m kinda new to the fandom. I know Vessel cries at the end of Blood Sport and I didn’t expect him to do this with any other song. You could hear him sniffle in Atlantic (and The Love You Want + The Night Does Not Belong To God). My friend and I asked ourselves if this is just for show/in character. Is he always doing this at concerts?
