OK, this patch makes much more sense than the previous one
-perhaps because this has become an isolated change.

I liked a single pass over the list of transaction rows more,
obviously (sorry Vova). 

Could you please return to the idea of the previous patch? 

/*
  0 - count of local rows, 1 - count of remote rows
  We need two different counters to make sure that local and
  remote transaction is 
*/
int n_rows[2];

txn->n_rows[stmt->replica_id == instance_id] ++;

and then the same loop as in the previous patch?
