Absolutely right - my bad. I'm afraid my brain is wired to never ever use '=' or '<>' where either side can be null, even if I'm trying to make a point about exactly that :doze:
The really funny thing is, as I'm re-reading the question several times trying to find the "gotcha," I thought to myself, "You know, I'll bet the author meant for one of these to say '= NULL' and goofed up." 😀

NULL is not zero
NULL is not an empty string
NULL is the unknown
