I did not miss the word "OR".
My point was the confusing (at least to me) wording in the article: "....multiconductor cables are stacked or bundled longer than 24 inches and not installed in raceways".
We all figured we have to derate multiple conductors in conduit, in cables or not.
This is still true, and I never doubted it, I only questioned the choice of words: "and not installed in raceways".
As dlhoule suggested, how about changing the wording to: "whether installed in raceways or not". Then, it would make sense to me.
