It's not an every game thing - it's something Klopp has done with Dortmund a handful of times when he felt the occasion warranted it [I guess the weekend's game felt like one of those to him] - so don't expect to see it every week or every home game. He comes on the pitch after each game to shake hands with the opposition and our players alike and he's already made a point of taking the players over to the travelling fans to applaud them several times.
He's doing what comes naturally to
him, not what's natural to you or anyone else. It's part of what makes him different - I've said before that he's not like any other manager we've had and that's a good thing in my view. You don't like the outward show of emotion and that's fine, you don't have to
