There is nothing really darker or more sinister about it than what you mention Jezz.
It just acts as a joke upon the fact that the other players are so far behind Tiger they have a hugely reduced chance of winning when he is in the field- which I in fact agree with, and something which probably is the case.
The issue I see though is how is this mindset going to serve Stewart Cink for example when he is coming down the back 9 of the masters on Sunday level with Tiger Woods? The video although in jest just seems to act as a mental confession of Tigers superiority and with players thinking like that they will never be able to beat him and overhaul his world number 1 spot.
That's my take on it anyway. I personally would never want to openly concede that I feel I can't beat one of my opponents on any given week out on tour as it immediately gives you a psychological disadvantage- and let's face it that is something players do not need when stuck with the task of outscoring Tiger woods over four days of golf!
Also it does make Tiger seem a little conceited through allowing the advert to be formed as it is clearly saying he is much better than the others and all but unbeatable on any given week, which although possibly true- in the past has been something Tiger has avoided alluding to. To prevent either annoying his fellow tour players or coming across as arrogant and big-headed.
Again though this is just my pessimistic perception of the video
