Only sometimes it doesn't :-)

    $ foo="foo bar"
    $ bar=$foo

No problem with the space in the expanded value here!

    $ echo $bar
    foo bar

but of course:
   ls $bar
   ls: cannot access 'foo': No such file or directory
   ls: cannot access 'bar': No such file or directory

It's documented in bash(1):

  PARAMETERS
       [...]
       A variable may be assigned to by a statement of the form

              name=[value]

       [...] Word  splitting is not performed, with the exception of
       "$@" as explained below under Special Parameters.

but I find it confusing nevertheless.
