Part of the confusion is the recombination of synthetic or single aroma chemicals on your skin or in your nose.
I don't have a deep understanding of the technical process, but if the menthol isolate from Peppermint, Menthyl Acetate, is used in a fragrance, it can, depending on the amount and juxtaposition, be called a menthol note, or a mint note. One person's nose might read it as mint, another as menthol, or if the note combines with a different single note chemical, it might strike someone as a peppermint patty.
The creator might call it a mint julep fragrance, with peppermint notes, while someone else might have memories of mentholatum.
An interesting site explaining the complexity of combining aroma chemicals is:http://www.perfumersworld.com/
Click on "flowers" on the left and it will take you to the Jasmine page, where they discuss the varieties of chemicals, some of high quality, some not, of reproducing this fragrance artificially. The Hedione they discuss is actually quite lemony, and is a way to get a long lasting lemon-like undertone. So when they market this, do they call it a jasmine or lemon note? They can go either way, I believe, depending on what they are trying to achieve. But it doesn't mean our nose will cooperate with their intentions!
My explanation of this is quite amateurish, I'm sure, but you get the idea why it can be marketed with differing note lists. When you break fragrances down into single notes, then recombine them in different ways, it plays much more to the imagination.
And of course, part of the game is to lure the buyer without disclosing *too* much. So there are many other notes in there to be teased out. My nose is very sensitive to opopanax. I can smell it in a fragrance in very small doses, rarely given on the ingredient list. So if opopanax is used in levels high enough to be considered a marketable note, it's already way too strong for my nose. I think that partly accounts for why one person will consider a fragrance a strong rose fragrance and another will say she didn't smell any rose in it at all.
