I think that was part of the misunderstanding of the spec. I think the
spec means it to be within one statement (and its associated immediate
actions) rather than rest of transaction. I think it's mostly to
prevent loop cases A row 1 modifies B row 1 modifies A row 1 modifies ...
However, I only looked at it briefly a while back.
