Re: MBC inline w BPC - I don't understand

I have been reading about the MBC for quite a while, and I have installed one on my 99 9-3 (and strongly recommend it), but I don't understand the logic behind installing an MBC inline with the BPC.
I can see two scenerios:
#1 MBC before the BPC. In this case the MBC would stop all flow before the BPC. Therefore the ECU would be opening the BPC, but nothing would flow as the MBC would be stoping everything before it could reach the BPC.
#2 MBC after the BPC. In this case the ECU would open the BPC, and the boost would flow but once again it would be stopped by the MBC before it reached the wastegate.
In either of these situations I would expect the same results as using an MBC alone. Obviously that isn't the case, as many tried it, and claim it works.
So, could somebody help clear up my mistunderstanding on this one ??
TIA
