If the fonts are contained in the graphics file, DVIPS cannot reach in 
to manage and revise any subsetting done by the graphics program.  There 
is no guarantee that DVIPS would even have access to those fonts, but in 
your instance it clearly did.  So DVIPS did its own subsetting, and the 
arbitrary list of subset references did not happen to be the same as the 
one embedded in the graphic.  When you use -j0, you turn off subsetting 
altogether and embed the entire font in the PS file.  That leaves only 
the subset already supplied for the graphics file, and there is no 
confusion.  For many years I had to do that with the Monotype Superfont 
for Times Roman, because its subsetting conflicted with another Times 
Roman font in the same document.
