As I said in the bug itself, by using red and green we are (accidentally) making a moral judgement about the revision. Humans are hard-wired to see red as bad and green as good (blood vs. forest/life). Revisions are, by their nature, amoral - so tagging one as "bad" and another as "good" goes against our purpose.
Well, in that case, the author of the revision is saying that "old" was bad so it changed it to "new", which it considered good.
However, that's not how it is showing. The "old" background is yellow, and the "new" one green. Red foreground is used *on both sides* to mark changed text.
