They increace mid range, as the piston moves there is a time although breif where the charge is moving into the upper cylinder from the cases. Where the reeds are not actually shut and the blow back is held in the boost bottle. Then on the next cycle there is charge ready and waiting to fill the cases.

As to real benefit. Dunno really. Supposedly boosts mid range. The balance pipe on LC motor inlets works in a similar way.
