Does the air flow meter count the air that is recirculated like DSMs so it is bad on your engine to vent into the atmosphere?

I've read that it is counted. However, I assume there is an error margin allowed in Subaru's ECU's because you can cap of the recirc tube and the car will still run well. We experienced a slight idle drop but nothing as drastic as a DSM with an aftermarket BOV and capped recirc.
