I'm still hanging with the comics, at least through #40... but yeah, this is all bang on, I think.

FWIW: I'm not a comic geek, but I did watch Watchmen (and buy the book). Buffy floating cross-legged is a reference to Dr. Manhattan on Mars, and we get a Rorschach mask in the opening panel to #34. So in this case I think it's actually a theme. There are obvious resonances between the current arc and Watchmen.
