Yeah, maybe I should have said "right or outer join". What I wanted to make
clear is that if you want to identify non-matches in the large (fragment, or
left side) you can still use fragment-replicate join. If you want to identify
non-matches in the small (replicate, or right side) you cannot.

Not quite. EXPLODE would take a record with n fields and generate n records.
I understand you point and it makes sense.
The graph in Alan's book says that if you "outer join on the small

Maybe this sentence is not clear enough :)
