Because they switch the placebo and creatine groups :)

    Week (-∞)-0: Noone has taken any supplements
    Test 1.
    Week 0-6   : Group 1 gets creatine, group 2 gets placebo
    Test 2.
    Week 6-12  : Noone takes any supplements
    Test 3.
    Week 12-18 : Group 1 gets placebo, group 2 gets creatine
    Test 4.


Thanks. I guess I have a problem reading closely.
