Reminding is different than being the same. For example, Big5/OCEAN/FiveFactor model uses factor analysis which has statistical reasoning behind the number of factors. In fact, the semantic meaning of the factors comes up after the analysis, not before. It's the same as clustering or GMM, the semantic meaning of the clusters is applied after the partitioning. The concept of partitioning people is the same, however, the order by which meaning is applied is opposite which makes them completely different in practice.
