CoD4 in 13.1 seconds tutorial video: What is the point?

Ok Mastermind has supplied a video in where he shows us how he completes CoD4 in 13.1 seconds, the how to do it yourself tutorial video below shows in slow motion of how to line up and what to do.

Personally must admit the video will help a lot of gamers but what is the point? I mean nearly everyone I know plays Call of Duty 4 online and the opposition will be moving not a still target as is in the video.

Ok it is only the training side, but why spend so much time on one thing. Watch the video below please and it me know what you think?
