I guess yes. To be very specific, it's the before-string and 
after-string properties mentioned on 
http://www.gnu.org/s/emacs/manual/html_node/elisp/Overlay-Properties.html.

Okay, we'll wait. But please note that we are interested not in the 
reordering of the text inside each property, but in the text inside the 
properties participating in the overall bidi algorithm and reordering of 
the underlying text.
