Oh, indeed, sorry for being dense.
That's indeed a bug.  You could try to work around it with something like:

(defvar lua-font-lock-syntactic-keywords
  '(((lambda (limit)
      ;; font-lock sometimes fails to erase the `syntax-table' property before
      ;; calling us.  So let's make sure it's clean before moving on.
      (remove-text-properties (point) limit '(syntax-table))
      nil))
    (lua-match-multiline-literal-bounds
     (1 "!" nil noerror)
     (2 "|" nil noerror))))

Also, I recommend you use syntax-propertize-function when available.
It comes with various advantages (e.g. it also works when font-lock is
disabled).

PS: BTW, do you have any news about the copyright status of lua-mode
that would prevent including it in GNU ELPA?
