I tried 'y' as well as 'n' and there was only a single query both times.
I also re-did the test with 
(gdb) p foo(3) + bar(4)
with each method changing a different memory location and I was able to see
that when pressing 'n' neither of the memory location was change, while when
pressing 'y' both memory locations were changed.

It's bullet-proof! :-)  
(except for nquery and frontends :-O)
