[Gimp-docs] rotating path?

[Kolbjørn Stuestøl <kolbjoern stuestoel no>]

In gimp-tool-transform.html (src/toolbox/transform/common-features.xml) 
there is a note:

     "When rotating a path, Preview options are not valid: only Outline
   is active."

What does this mean?
I am not able to rotate any path set with the path tool.
Perhaps I have missed, forgot  or misunderstood something?
