The note in REmake2 is code - I think it was in an interview with the scenario writers that they confirmed it, but even without it's so "not Chris" in the note that it should come across as very strange. It doesn't confirm Chris's taste in women though, only that he wrote what he hoped the right people would read, while others would dismiss.
And as for Rev2 - I love the way the game references several lines from the OG RE1 (Jill Sandwich, I have THIS, etc) as it stabilizes that Rev2 is in the same canon as the OG game and not REmake. Neither of those lines are in REmake. I thought that was a nice touch, as someone who prefers the OG game to REmake (if only we'd get a remaster for modern consoles).
