At 20 feet and up, it does. It is not nearly as much flow as you are used to, but it is enough. You need to consciously breathe a little slower and longer, but it works just fine. Another thing, I wouldn't call this a std BCD type connector, as the holes on the end are bigger.

Air Buddy for a BCD
I bought one a year ago and it acually works. I only used it on a few occasions to test it. Downside is it has to be more or less premanently added to the hose.
