There is no extra address range to add a second SID for 'full independent' control. I believe that a SID2SID is somewhat of a waste in that there are other tools capable of making mono into stereo. In a sense, all softwares work with it.
The 8bitventures description doesn't make it sound that way:
A second SID (C64 audio circuit) gives you 6 voice polyphony/6 tracks when using the MSSIAH Sequencer and Drummer applications.
With the MSSIAH Wave-Player you can assign an extra output for your samples to the second SID. MSSIAH Mono Synthesizer and Bassline echoes all audio to the second SID for stereo output.
Are they just full of shit?
EDIT:
Looks like $DE00 is the starting address to use for SID2SID SID 2. Which is different from $D400, which is where the regular SID starts. So you can certainly address both chips seperately.
As proof, here's a video of a guy/gal showing 6 channels of SID using sid2sid: https://vimeo.com/3341109
