It's DIR because after doing longer dives and sitting on deco (especially in the overhead) there isn't a lot of room to move around and stay warm, so yes, you blow more air into the suit.
...
I've got a longer dive coming up and the last time I did deco at this spot I got a bit chilly. I'd like to have a way to add more gas to the suit for my deco.
1) why not just wear 2-4 pounds more weight on a V-weight or tail weight? seems a bit simpler (to me)
2) What is "DIR" may well change if you have 20+ support divers coming down to help you change into/out of harnesses, provide weights and help in emergencies etc. compared to most of us conducting dives on our own ...
If you are cold now... Would you be able to vent even more suit gas and stay down to complete your deco (without the weights) if you lost all your backgas gas?
You might be too light for this possibility and if so should be adding weight - not drop weights which could be stolen or moved, etc.
