I have an idea or two but want to see if it matches anyone else's ideas.
My guess is,that it's about the 'acoustic' signature of the boat,which an electronics officer aboard an 'enemy' vessel might pick up as an anomaly, when dived.
At zero-yaw of the rudder,the water coming to it would be 'clean',as well as the water coming off it.
A common 'slot' between the two might generate more 'noise.' Potentially 'deadly.'
