I agree. I don't think it was a factory option. I am sure there was suggestions and sketches from chrysler that were considering its use (which the article alludes too) though.

I also recall reading somewhere that the designer behind the 71 B body style for the charger was not a fan of the bumble bee stripe which is why the longitudinal stripe was used for the 71 body style change...not sure where I recall hearing this, but its one of those rumors that makes sense. A bumble bee stripe on this body does look a bit odd.
