   It's not the same blank node. `BNODE("...")` is per row (solution mapping) at the point of execution and the two arms of UNION are different rows.
   
   ```
   CONSTRUCT { ?b <p> "x" } WHERE { BIND (BNODE("b1") AS ?b)  {} UNION {} }
   ```
   !=
   ```
   CONSTRUCT { ?b <p> "x" } WHERE { {} UNION {} BIND (BNODE("b1") AS ?b)  }
   ```
