He wrote about this when it came out, I'll paraphrase:
The video's and the article were meant to complement each other to show different takes on the same system
The system is to go through 5 exercises for the same strength pattern (press, bench, dead lift, squat) that fall along the various points of the strength-speed continuum: Overload ~> Strength ~> Strength-speed ~> Speed-Strength ~> Explosive ... The descriptions of which are in the article.
You could create dozens of different complexes knowing the system as long as they follow the outline above
So dont worry about the vids being different, its actually a good thing because it shows you 2 different exercises/complexes that both follow the rules. Use them both to understand the system and you might even be able to adapt it to your specific needs.
