That's "pro-set" and it's just an aid to getting the derailleur in proper position, not a solution to your problem. It will not change anything about the way the derailleur adjusts, but merely shows you where the proper position is. Some pics from the side of the bike directly across from the front derailleur, directly above the derailleur, and looking from behind the rear cogs toward the front derailleur at the level of the chain would help. Better would be in-person assistance from a bike co-op, a friend or a bike shop.
The explanation is wrong - you pull down firmly on the cable AFTER the initial tightening of the bolt, then you loosen it, pull up slack and retighten. The pulling procedure is to help everything seat in properly, and will usually produce some slack in the cable, which is why you have to readjust at the clamp. Some people call the procedure pre-stretching but it does not really stretch the cable.
