Don't ask me either....
It makes me wonder if the bike was running, but voltage still low, maybe the voltage wasn't sufficient to operate the horn. I'd charge the batter up full, then watch voltage and see if it drops. If it does, maybe remove a wire from the battery and see if it drops when not connected to the bike, which I'd guess indicates a bad battery. Good luck there.
