I've now received that 20th Anniversary Edition thing, I should do a 4-way listening test between these two versions and my original and the 1999 remaster (I need to dig those up from the basement). But at first listen the Alternate Mix doesn't actually sound that different - not in the way that for example the remastered/remixed "Individual Thought Patterns" does.
