To be fair I've had something similar happen before where the gate was so crowded my boarding pass was scanned but there was no room to step forward. When the queue cleared I started to walk forward but she stopped me and asked for my boarding pass, I told her she'd already done it but she still wanted to scan me again. It of course beeped and she just said thankyou and I kept walking thinking nothing more of it (until now!).
So I can see how gate agents might understand that 'already boarded' message to mean 'oops you accidentally scanned this person twice'.
