Glycolosis and Fermentation

Ok, so in Cliffs it says that in alcoholic fermentation "The purpose of the fermentation pathway, then, is to release some NAD+ for use by glycolysis. The reward for this effort is 2 ATP from glycolysis for each 2 converted pyruvate."

My Question is if one molecule of NAD+ is produced for every pyruvate, then shouldnt we get 2 ATP, instead of just 1? Because after glyceraldehyde-3phosphate dehydrogenase turns glyceraldehyde 3phosphate to 1,3bisphosphoglycerate, that goes on to form 2 ATP (steps 7 and 10). Therefore shouldnt we get 2 ATP for each Pyruvate? OR are they already taking into account the 2ATP that are used in steps 1 and 3?.......I think its the latter, but i just wanted to confirm.

The 2 ATPs used as phosphate donors in the phosphorylation of glucose and the phosphorylation of F-6-P are taken into account when calculating the total ATP yield.
