Is it ProLogic encoded?

 Yes, it's a ProLogic encoded track.

I've never understood how a presumably pure stereo track can become a 2.0 surround track.  Where does the matrixed surround sound come from if the source is two channel? 

I think it's the name "Dolby Stereo" that confuse you, an optical 35mm Dolby Stereo track isn't just two channels, it's a four channel configuration; Left-Center-Right-Surround.

I also don't understand why the other mix on the BD is 4.1 and not 5.1.  If it comes from a six-channel mix, why is it not 5.1?

hairy_hen described it better than I can do here: http://originaltrilogy.com/forum/topic.cfm/Ultimate-Trilogy-Set/post/567939/#TopicPost567939
