Wasn't the one long also a call from the engine crew to the conductor to check if a stop was to be made? This would be followed of course by the corresponding whistle signal acknowledging the conductor's signal to stop or to highball?

As an aside, the one long, one short is still used by some as a warning signal when approaching MOW.
