The link you mentioned, basically changes the behaviour, by tagging the temporary tables. If they are tagged, they will be loaded (promoted) in memory/LASR. And that is the difference. Once loaded, you can see them into LASR as regular tables.
NOTE: The temporary table _T_BE5C2602_45A0DCB8 was successfully promoted to the
LASR Analytic Server table WORK.SUM_BY_COUNTRY. You can access this table with
the TABLE statement as table EXAMPLE.sum_by_country(tag='sales').
