I'm not only "apparently referring" to that list, I pasted it verbatim
in my reply to you :)

It doesn't state an order.  It describes the mapping from SID to
uid/gid, and there's *no* order at all to it, just a description how
certain SIDs are mapped to certain uid/gid values given numerical

Windows usually maps SIDs to uid/gid values?

Both sections have examples.

What is a "typical" order?!?

If you login locally to a domain member machine the default domain is
the logon domain of this machine.  If that's not what you want you have
to choose the logon domain of your account explicitely, even if it's the
local machine SAM.  Windows will not try to find the user name locally
if you didn't chose it explicitely.  You get "The user name or password
is incorrect. Try again" instead.

The only exception I'm aware of is the "Administrator" account, at least
in Windows 10.
