Quite confident. The trees are built in that fashion, and (post-)pruning essentially undoes some of those splits. Some more reading: scikit-learn.org/stable/auto_examples/tree/… (you could rerun that and add plot_tree, maybe), rdocumentation.org/packages/rpart/versions/4.1-15/topics/…, en.wikipedia.org/wiki/Decision_tree_pruning
