Being a transition metal has nothing to do with oxidation state, it has to do with the electron orbits filled to balance the the number of protons in the nucleus rather than the number of electrons any particular atom has at any given time.

His statement, that I quoted, spoke of lead, not lead oxide.

Just nit picken.
