I don't think there's an official divergence in terminology other than the version numbers (which have mostly stopped incrementing for FSD vehicle owners, meanwhile there is a lot of work going into new iterations for the version running on tesla's robotaxi fleet)

Then I struggle to understand what they should have acknowledged here concerning the software used? That they do not have access to a version of FSD which currently isn’t accessible to the public? I’d think that’s self-evident for any Organisation not affiliated with Tesla.
