Try this analogy: My sofa is blue. My shirt is blue. That doesn't mean that "my sofa" and "my shirt" are colours, or that they are the same / equal. In the same way, saying that <exp1> is null and <exp2> is null does not mean that <exp1> = <exp2>, or that they mean the same, or even that they denote the same kind of thing. I use "null" as an adjective, like "blue".
