There are two ways the case can "stretch" between loads. The most likely is when firing. The slight gap of the head space and the ability of the neck to "flow down" the barrel. Brass does return but not all the way.

To a lesser degree (i.e. very seldom) when working the brass through the resizing die the brass can also stretch.
I don't know if its just me being pedantic but I am adverse to knowing that my batch of rounds have differing case lengths.
