Should DELETE {URI URI * } not update all matching graph patterns?
No.
(and that's bad syntax)
DELETE {<URI> <URI> ?x } is bad syntax?
"*" is bad syntax.
DELETE {<URI> <URI> ?x } is bad syntax for another reason - there must
be a WHERE.
I had a case where only DELETE {URI URI NODE } did execute the update in
the dataset/graph/query fuseki UI.
To be precise it is a DELETE INSERT combination with an empty WHERE
clause.
DELETE {pattern} INSERT{pattern} WHERE{ }
the "pattern" is used as a template.
DELETE {template} INSERT {template} WHERE {pattern}
If the template has variables, these variables must be set by the WHERE
clause. Otherwise triple patterns with unbound variables are skipped.
There is no pattern matching in a template.
There is a short form DELETE WHERE { pattern } which is
DELETE { pattern } WHERE {pattern}, using the pattern as the template.
