I wouldn't worry at all if your bike came factory set up like this. The video does also specify that if your bike didn't come with one, it's because it don't need one (which is logical, otherwise you would have one). I'd trust your manufacturer; its engineers are a little more educated than we are.
It's also funny how the guy in the video doesn't use a torque wrench. May be that's because the plug prevents the overtightening. Still, I would use one...
