Should my employee HSA contribution be reflected on line 25 of the Form 1040?

I understand that on the W-2, 12b W reflects the total of both employer and employee HSA contributions. However, shouldn't the amount that an employee contributed be a benefit on line 25 of the Form 1040? Such amount would flow from the Form 8889 line 13, assuming that the amount on that line is less than line 12 of the Form 8889.
