you misunderstood
the point is that

  hypothetical_smart_ptr<int>
    p = new int,  //allocating data
    q;
  p = q;  //data intended to be shared now
  delete p;  //equivalent to 'p.reset()' in the 'shared_ptr' case
  delete q;  //<--actually releases allocated data

it deletes or otherwise releases guarded resource only if no other
smart pointer holds a reference to the resource
