What is an ARV's function if the EGR is disabled?

I have my EGR hooked up to a clean air filter and my exhaust port is blocked. My ARV is getting good vacuum to it though, so it is functional, what is it doing if the EGR is on a clean air filter, or even if the EGR is disabled/deleted? Also what is this inlet people refer to?

More debate than answers, but this is a thread I found back when I was messing with mine:

DIY-disabling EGR and Air recirculation!

I don't have a California car, yet I do have an ARV, so that's one myth busted right off the bat. With EGR disabled I noticed really bad mileage until I also disabled the ARV (didn't know the two were related at the time). I'm still curious as to why though.

if the egr is disabled, the ARV will simply be a wastegate that dumps its air into the inlet side of the turbo.
