dagop: simplify dict/set reuse condition in subsetparentswalker...

dagop: simplify dict/set reuse condition in subsetparentswalker Prepares for fixing the calculation of p1/p2 sort keys. With this change, there will be one more copying on merge&fork case. I think the copying cost is negligible since we'll have to update each item in the dict on merge/fork.
