No, it doesn't mean that.  It just means the display will start at the
left window boundary, even if the item includes R2L text.  To
illustrate, you will see

* foo
* bar
* OOF
* RAB

(where "OOF" and "RAB" are R2L text typed as "FOO" and "BAR",
reordered into correct visual order), rather than

* foo
* bar
                                                                    OOF *
                                                                    RAB *

with the default (nil) setting of bidi-paragraph-direction.  I think
the latter is ugly anyway.

The variable that controls reordering is bidi-display-reordering, and
it must stay non-nil if we want to support R2L text.

The Emacs manual and the ELisp manual have more information about the
meaning of bidi-paragraph-direction, if you want to learn more.
