It is not false! Delete an app from you existing new iPhone and then
reinstall the app, if you sync after doing this, you sync, you don't
restore from a backup, hence the data is lost.

We described a situation were a new release of an app requieres a
release of iOS that is not available for the iPad. When using iTunes,
the Apple servers are not involved, there would be no traffic at all
and the user would get back therequired old releaseof the app.
