That's not quite right, is it?  With -k 3b, 'sort' ignores leading
blanks in the 3rd field; but with -f2, 'uniq' treats those blanks as
significant.

Also, the details about field selection get in the way of the basic idea.
How about the following wording instead?

  Note: 'uniq' does not detect repeated lines unless they are adjacent.
  You may want to sort the input first, or use `sort -u' without `uniq'.
