Hi all,
Hi Sarven,

That seems like it ought to fail: you're try to load into the default
graph, but that's the union graph.
It probably ought to fail but it doesn't :-)
The union graph only exists at query execution time. For anything else,
the system sees the real, concrete storage default graph; that includes
the API because the API can add triples. And SPARQL Update templates.
Use a named union graph to get the union via the API.

Hmm.
