But this doesn't help seeing facing pages preview in Bridge from our InDesign files
In my example the individual spread is a single page 17x11, which shows all of its content in the Bridge preview (to the right in my capture). Its being placed as a crossover on a letter sized facing page document, which you would use for export.
I was assuming the reason you don't set up the spread as a single page is that eventually you need two pages for imposition. Placing the single page ID doc onto a facing page spread would let you export two single pages.
I think CS4 was released in 2009
