Good question!

There was a huge amount of debate regarding bass management with the 950 around the time that they first started shipping units in early April. One part of the debate was bass management and the stereo bypass mode. It turns out that the 950 does bypass a full-range signal from the analog input to the volume control and on to the pre-amp outputs, but it also tosses that signal into the digital domain and applies bass management if the mains are set to small to produce a LFE signal and discards the rest. The result is an analog bypass for the mains, plus (if the mains are set to small) a digitally-extracted subwoofer signal.
