"Loss of down" is really a misnomer - it's actually "loss of the right to replay the down." See the most important rule in football-Rule 2, specifically 2.7.2. This is an important distinction, especially in a play like this one. Team A does not loose first down. They loose the right to replay second down.
Also see 5-2-2 (last sentence): The loss of down aspect of a penalty has no significance following a change of possession or if the line to gain is reached after enforcement.
