You are not using the && in the right place. If &J=1 and want the value of YY1 then you should do:
%let year_x = &&yy&j;
The first pass will convert && into & and &J into 1 resulting in &yy1. Which the second pass will convert to the value of YY1.

One counter example to your solution is

Adding as you have done would give the subsets

while the optimal solution is
