I thought that there was an algorithm (?) in PF3 which prevented the pilot and ATC voices being the same at any given time. Maybe not. Not vitally important, clearly, but it does sound a bit strange (like I am talking to myself - though now I come to think of it, I do do that real-world, so I suppose it shouldn't sound so odd!).
Log attached (I recall when being asked to descend to FL160 and then FL140, the two voices were identical).
