this is correct.
since dsg halves the cylinder volume because it's essentially a short stroke on each shot... if you run a longer barrel you would need more air in the cylinder to match the barrel volume.
The very rare instances in a full stroke setup you'd need one is in those guns that come with extremely long barrels over 450mm
I futz with V2s, V3s and V6s. I could be wrong... but probably, most likely not, as far as I know.
