No, you were quite clear that it acted on words, that wasn't my
question.  I used RBUFFER and LBUFFER as shorthand for "words found
after the cursor" and "words found before the cursor."  Now that
you've said this ...

... I see that the difference is whether you rotate the last word to
the front or the first word to the end.  But why would you rotate the
words in order to edit one, rather than just move the cursor to the
word you want to change?

Also it looks like this always rotates all the words in the buffer, so
e.g. the last word moves to command position no matter what word the
cursor is on.  If the reason is to be able to edit a different word,
wouldn't it make more sense to move the word at the end to the cursor
(or the word at the cursor to the end)?

I don't follow that at all.  How is rotating words an alternative to
moving backward by one word?
