That screencast is unwatchable! Why are there two people talking at the same time???

Lol, this screencast is horrible. It's just one guy talking, but they edited the cuts so close to each other that he's overlapping himself talking. I guess it's "saving time" or "is stylish and cool". Obviously it was a conscious decision on their point, but it's a horrible idea. I don't think I'd trust a company that would put out something this bad as an official video.
