I understand your confusion Michal. The deal is that while subjects
are conceptually disjoint from the event they are still stored
together with the event in the event table (as an optimization). Also
as Siegfried says - the event subject is a snapshot (like a normal log
statement) so it makes even more sense to store it together with the
event as we do.
