Why do extra work in ExecBRUpdateTriggers() to eliminate the false
negative case if we don't rely on it anyway? If we do need to rely on
it in subsequent patches, then we need to be sure, right?

I guess I'm confused about whether 0002 is introducing a new guarantee
or if it's just a convenient place to eliminate one source of false
negatives.
