Well, it could be the login OS name if the user connection parameter is
unspecified, right?


No.  It is always the user parameter.  It just so happens that parameter also has a default.  And so while there is a transitive aspect the resolution of the user parameter happens first, using the OS user if needed, then the dbname parameter is resolved using the user parameter if needed to supply the default.
