I saw - and still see - some differences, but this is probably off-topic.

However, what's on-topic is that I'm unable to see why DEBUG is supposed to be "confused". I also don't agree that it "incorrectly decrements (E)IP". If the conditions described above are met then (E)IP has to be decremented, it doesn't matter if the INT 3 was truly executed or if it was "faked".
