Where did you read this? I am not seeing it.

I always figured that a sleeping bag prevents heat loss above you, while the pad you are on prevents heat loss below. That is, the crushed down insulating in the bag you are lying on doesn't do very much.


Go to the link in the OP and look at the 5th picture at REI. It shows how the bag is designed to be incorporated with a sleeping pad.

And... yes I agree the bottom insulation on a traditional sleeping bag is dead weight you are carrying. Currently I only buy quilts (when I need a new bag... which isn't very often). My personal favorites for performance at a great price are from enlightened equipment.
