Well xor is linearly inseparable, which is impossible with a single perceptron. > Our models by contrast make tractable predictions for what popu- lation and single-unit neural representations are required to support compositional generalization and can guide future experimental work examining the interplay of linguistic and sensorimotor skills in humans. Do you see where that causes an issue with supervenience? Especially when mixed with STDP which could change that more? It is confusing the map with the territory. At least with the extreme strength of their claim.
