Good find, here is the text relevant to this discussion:
"... BlackBerry App World will assign unique identifies to applications when they are put up for sale.
The UUID is used to uniquely identify an application in the test/pre-production environment. Once you upload the application to BlackBerry App World, it is no longer used. Changing your UUID allows you to perform tests of your application in isolation of one another."
