I don't think this is a good change.  It replaces one perfectly solid, 
harmless, and readable line of code with six lines of comment explaining 
why the code isn't necessary (times two).  And the code is now less 
robust against changes elsewhere.  To maintain this robustness, you'd 
have to add assertions that prove that what the comment is saying is 
actually true, thus adding even more code.

I think we should leave it as is.
