I think quotation-referent distinction makes this sufficiently different from Liar. The referent of this sentence is the the quotation “This English sentence has six words”, which is not quite the same as the referent being the meaning of the sentence. It’s no more self-referential than “This sentence is written in black ink”.
I agree with you. That’s basically what I was getting at afterward in my edit. I’m just trying to dig up a statement which is unambiguously true, but yet isn’t at all useful. I think that “This sentence is either true or false” fits the bill.
