Not really. Obviously you need the %N form if you need more than 1 ;^)
I tend to use the %N form out of habit and the fact that I daily deal with
many recipes that have multiple patterns because we build stuff for
multiple architectures and multiple compilers all at once - ala

%1/obj/%2/%3.o
%1/lib/%2/%3.a
%1/bin/%2/%3

where %1 is the architecture, %2 the compiler, and %3 the target basename.
