• two languages, english and spanish for example
• two siteaccess, site-eng and site-esp.
  SA site-eng has english and spanish in site.ini declaration
  SA site-esp has spanish and english in site.ini declaration
  (respect the language priority order)

• 1 folder under root - people/personas (titles for each translation)
• 2 articles under the folder: 1 in english titled "Jack", 1 in spanish titled "Julio"

in eng siteaccess browse tro root, then to the "people" folder. verify these urls:
site.com/people/jack OK
site.com/personas/julio BAD

in spanish siteaccess navigation gives these:
site.com/people/jack BAD
site.com/personas/julio OK

so, the case is simple: if i'm on site-eng SA, and i have jack, john, james and julio the urls are:
people/jack
people/john
people/james
personas/julio

the last url should resolve to: people/julio

additional notes:

• people/julio is accesible typing the direct url
• an object that only exists in one language appears to "force" the SA to use the object's parent with the same translation
