That's a well produced video. I think that the guy not being very familiar with the saw could be viewed as a slight positive, as opposed to someone else using it that didn't make any mistakes. It gives it a little more credibility.
My biggest concern is where he is shown plunging the blade on a few cuts. The first one wasn't even a plunge cut, but he just didn't back the saw up far enough before the cut. That will quickly pull the saw to full depth unexpectedly, and is probably a fairly common mistake with new users.
The blind plunge cut could have gone south pretty quickly, but it was also pretty obvious that he had enough experience with saws to minimize it. Obviously he didn't realize that the black thing still in the Systainer was the backstop.
The rip cut without dust collection is actually pretty impressive, and shows how well the new blade housing design makes better use of the blade windage to channel the dust through the blade housing. The blade housing has a new channel incorporated around the perimeter and close to the blade plate, where the teeth of the blade are creating windage through this channel from the front of the cut all the way back to the dust port.
In the past, dust could continue following the teeth of the blade and return back to the workpiece at the rear of the cut. With this new dust channel, there is virtually no dust that doesn't get directed out through the dust port even when no dust collection is in use.
