We examine a sentential logic description, as based on set theory, in support of Suzko's theorem that only two truth values are required as a universal logic. Under syntactic notions, we evaluate three definitions (monotonicity, transivity, permeability) out of six definitions (trivial are substitution-invariance, reflexivity, combined consequence relation). Monotonicity and transivity are not tautologous. Right-to-left permeability is not tautologous. What follows is that a Malinowski extension of mixed-consequence by relaxation of the two values for three logical values is spurious, especially due to the fact that Suzko's theorem is a conjecture based on the assumption of set theory. What also follows is that compositionality as based on Suzko-Scott reductions are not bivalent and exact, but rather a vector space and probabilistic. Our results point further to the equations analyzed as being non tautologous fragments of the universal logic VL4.
