You are stating the same thing JOG did. Only you are stating it in a overcomplicated and basically wrong way

--> A Row does not have attributes, A relation does. You are redefining what the meaning of an attribute. --> Tuples are propositions validated by true in 2VL *only*. Your logic is vague N-VL.
--> The chances such vagueness may allow to define a logical operator such as JOIN demonstrate one thing. You have no clue of what constitutes referential integrity and domain of values.
