I don't understand that either. I have converted 9 Volvos with Super 10s. I currently own two Super 10s and one straight 10. Two of them are conversions in progress.
We know that on a straight 10, a range change takes place by flipping the lever up when shifting from 5th to 6th, or visa-versa.
My Super 10 stickers say there is an automatic range change between 6th and 7th too. I can't discern any automatic range change. I guess all that matters is that they work great.
