You have two interfaces which export the same onboard interface index. There is not much udev can do here; the only option is to disable onboard interface name policy. The attributes that are used by udev are "acpi_index" and "index". Check values of these attributes for all interfaces.
I will check, but please note that I didn't enable this. AFAIU Debian uses the settings according to the guidelines of upstream.
As is obvious from the log you provided, they did not "keep" their names but were renamed. Whether this is correct depends on rules your distribution is using.
AFAICS the kernel of today still assigns the "legacy" interface names, which are renamed by udev later. I would suggest to improve conflict handling in udev, e.g. by falling back to the "non-onboard" interface names for renaming, instead of an exit(1). This makes sure that only the on-board interfaces are affected, not a random set of interfaces depending upon the discovery sequence. Regards Harri
