the fresh air is trapped in the transfers, the longer the transfers the more that is trapped and the cleaner it runs, too much air and you can't get enough fuel in the cylinder. the fresh charge in the case is richer then a normal saw and mixes with the fresh fuel in the cylinder.
the big problem with this whole mess is the fresh charge still enters the cylinder while the exhaust port is still open. not a lot saved but some.
for the most part all it does is dilute the exhaust with some fresh air. makes it pass epa regs
