Database-Role settings behaviour and docs mismatch

In the docs it says
"It is also possible to tie a session default to a specific database
rather than to a role; see ALTER DATABASE. If there is a conflict,
database-role-specific settings override role-specific ones, which in
turn override database-specific ones."

Whereas in process_settings() the sequence is this

ApplySetting(databaseid, roleid, relsetting, PGC_S_DATABASE_USER);
ApplySetting(InvalidOid, roleid, relsetting, PGC_S_USER);
ApplySetting(databaseid, InvalidOid, relsetting, PGC_S_DATABASE);

which looks to me like database-role specific settings are overridden by
both user and database specific ones, in contrast to how the docs
describe this.

Am I confused, or is this a problem?

Not that bothered, but seems like the docs provide more useful behaviour
and the code less useful.
