I hadn't thought about the similarity. While I don't perceive them as strikingly similar, I do think you're right that they have some DNA in common. Likely, it's some sort of smodern resinous chypre base (including patch), which they both share, plus the rose. In fact, curiously, the sales assistant in the Parfums de Rosine store suggested me Folie de rose when I told her that my mom wears Aromatics Elixir. And Aromatics Elixir is the prime resinous patchouli chypre (though it has no big rose).
