Are we really going to get bits and pieces of Smullyan's book plastered
all over the net?

No, the two statements are not logically equivalent, by any possible
interpretation that does not include a screenful of caveats.

This is just one of many levels of errors in Smullyan's book.
He took a course in logic once but cut the first three classes (so it seems)
and then wrote a book about it.
