I don't know if this in particular is made up or not. But tasting notes, especially of the marketing kind, can be a collection of notes from different preparation methods, consumption temperatures, and, most likely, from being drank next to other coffees that taste different and might bring out each other's individual accents.
I think almost anyone could tell the difference between different coffees side by side. I just don't think people are super focused on the coffee flavor when they drink their regular brew.
Where you have to be careful is when boiling the water yourself for a chemex or aeropress brew. Done right, those are better. But I can't be bothered most days.
Assumes they're roasted nicely, otherwise it's comparing ashtrays with pencil shavings.

Cocoa, chocolate, brown sugar, Graham cracker... These are all notes that I want my morning latte to taste like.
Berries, lemon, floral, citrus, melon... These are all flavors I can do in a cold afternoon coffee, but otherwise taste really sour to be.
But it's just two categories for me. I couldn't distinguish any of those flavors individually.
Maria's husband Tom writes the tasting notes for each variety, such as...
Rwanda Dry Process Macuba
"Berry notes, floral impression, ripe blackberry, blueberry, fruited acidity, darker roasts tie in delicious bittersweet undertones, like strawberries dipped in chocolate sauce."
Yemen Al Qafr Hawari
"Sweet, somewhat rustic, notes of pistachio cookie, malted chocolate, ginger powder, sesame candies, corn syrup, tobacco leaf. Super chocolatey dark roasts."
I swear (even though I know I'm wrong) that he just makes this stuff up.
