I recall a discussion on this topic recently. I believe that someone who
knows the spec better than I do said the formal definition doesn't prohibit
redundant triples, so a conformant program would not necessarily delete
them...

If I could recall when I discussed it I might be able to provide an answer
with more supporting documentation, but I can't seem to find a trace of it
now.
