Could it be a marketing or manufacturing mistake with the FeCr tape?
I was thinking that they meant the older version of Agfa Superchrome tape, where there was real FeCr tape, but then again there is Type I cassette detection.

Other than that I digress, but again the Agfa Carat FeCr cassette in my collection is filled with ordinary ferro tape
