Modern sonar has a fixed bafflle behind the sonar mount, as they are more sensitive and would pick up propeller noise at any angle. I'm fairly sure the Germans didn't have fixed baffles.
You should still be able to hear the propellers at 180 ish though - can you not?

I think he meant whether you can hear something "in the imaginary baffles", i.e. the aft sector. I don't think the baffles were introduced with the GHG yet. But an interesting question who might have come up with that first?
