Based on this diagram, the organism is classified based on some similarities. In the upper-division, the similarities should be more general in the lower division, the similarities will be more specific. It was mostly based on an organ, for example: vertebrate.
An organism with the same phylum could be put in a different order.
But the organism with the same order should have the same phylum and class too since the order is located below the phylum. Those similarities are tightly correlated with the evolutionary relationship.
