No, if that override isn't set, it uses the same hostname value that you 
get when you run the hostname command.

But, as described in the comments from the mysql.txt, above, it's just 
an override for when your hostname isn't correct.  You don't want--nor 
need it.  Just comment or remove that line.

I'll admit that the comment doesn't explain how it works--but then 
again, doing so would require explaining how settings work and a lot 
more, so it probably doesn't make sense to make it more descriptive.
