You seem to believe that a nested hierarchy requires rigid ranking, such as seen in Linnaean taxonomy.
“During the four years of our absence, I sent home communication after communication to the 'Linnaean' Society, with the same result as that obtained by Noah when he sent the raven out of his ark.
The shore-dwelling Fuegian savages used a lexicon of more than 32,000 words that was a "labyrinth of the particular," Chatwin says, including names "as complex and precise as Linnaean Latin of everything that swam or sprouted, crawled or flew."
The term "clade" did not exist in the older Linnaean taxonomy, which was by necessity based only on morphological similarities between organisms.
The concept embodied by the word "clade" does not fit well into the rigid hierarchy that the Linnaean system of taxonomy uses; indeed, cladistics and Linnaean taxonomy are not really compatible.
Linnaean taxonomy demands that all organisms be placed neatly into a rigid, ranked, hierarchy of taxa, such that one individual kind of organism must belong in one of each of the categories: species, genus, family, order, class, phylum and kingdom.
Because the Linnaean system is not based on evolution, most biologists are switching to a classification system that reflects the organisms 'evolutionary history.
Because of this necessity to "file things away neatly", the Linnaean system is often very convenient indeed in organizing such things as large museum reference collections, however it does not represent well the process of change that actually happens over evolutionary time.
But this is not the same classification as the Linnaean Reptiles.
In other words, the nested hierarchy of the observed Linnaean taxonomy is explained as due to the nested hierarchy of the posited descent from common ancestors.
