What is the purpose of `--sync` with `xdotool mousemove` command?

manpage of xdotool says




--sync



After sending the mouse move request, wait until the mouse is
actually moved
. If no movement is necessary, we will not wait. This is
useful for scripts that depend on actions being completed before
moving on.



Note: We wait until the mouse moves at all, not necessarily that it
actually reaches your intended destination. Some applications lock the
mouse cursor to certain regions of the screen, so waiting for any
movement is better in the general case than waiting for a specific
target.




I don't quite understand the purpose of --sync with mousemove command.



When a script "depends on actions being completed", does the script necessarily "actually move" the mouse, so that mousemove command can start to be executed?



Is there some easily understandable example?



Thanks.
