| Does a query submitted with "CONSTRUCT *" always return a graph
equivalent 
| to a query submitted with "CONSTRUCT p", where p is the query pattern 
submitted?

No...

| If not, why not (e.g. please show counter-example)?

The GRAPH stuff complicates life:

CONSTRUCT * WHERE { GRAPH ?g { ?doc dc:title ?txt } }.


So it's been taken out...
