That's not true, if Lauda would be on DT1, Lauda would be excluded. Lauda has 20 inclusions and 28 exclusions from DT1, but because 8 of those DT1-members have more exclusions than inclusions from other DT1-members, their vote for DT2 doesn't count. However, since their vote for DT1 still counts, it means Lauda wouldn't be on DT if (s)he'd be on DT1.
