Haven't you read the news accounts? AA filled out the paperwork. Not the agent. And they updated the paperwork when they moved him from his original flight to the flight in question. And they crossed out one flight and put in the other, which is the original discrepancy the captain complained about. It was AA's issue, not the SS agent.

The captain was just using this excuse to put him off the plane. Actually, (this is pure speculation now, based on my own experiences with AA FA's lately) I don't think the Captain was afraid of anything. He was just backing up his FA who was scared to death of an Arab with a gun.
