Your xyl is right.  I've seen this in many instructions for jumper cables 
and so forth.  The idea is if you disconnect the ground first, if the 
rench accidentally touches ground, no problem.  If it does while you're 
unhooking the positive wire, you get a short.  If y ou unhook the ground 
first, even if the rench touches ground, nothing will happen.  Hope that 
makes sense.
