He means this will cover all the key attributes.
I've looked on a few first programs, and they're nice if you don't want to spend some time to think about training, so good job! But there're also a few problems.
The first problem: players from the same position don't need the same training simply because they don't have all the skills on the same level. One may need passing while another needs crossing.
Another problem: what if I have, let's say, MC/AMC/ST player? What program should I choose?
But the main problem is that the schedules try to be balanced, but in fact they aren't. Yes, they cover all the skills, but some of them got 5% of total XP, while others got 15%. For instance, GK. 5% to Anticipation and Rushing Out but 18% to Punching. That's a huge difference!
Balanced training sessions suck, they're mindless and lazy ::/ It really is way more effective to focus on a few skills you want to improve, and when they're ok, focus on another.
