I've verified that this is in fact the case, however, fixing this for
multi-page output might be difficult since Ghostscript opens separation files
as it comes to new spot colors.  

I was hoping this alternate command line might work:

  gswin32c.exe -sDEVICE=tiffsep -dSAFER  -o test.%d FullSpotDiff.pdf

However this doesn't produce the correct output for the 2 second page either
(the test.2.s0.tif file appears to be the second page of the first spot color,
though it's hard to be 100% sure since this is a pretty poor test file, having
no content other than full pages of the spot colors):
