No he isn't. Lisp has no provisions for turning single-quotes into
double-quotes. What he wrote is actually equivalent to:
(add-hook 'sgml-mode-hook
'(lambda ...))
because Lisp doesn't care about the presence or absence of whitespace
before or after quotes.
But I agree that his layout suggests a serious misunderstanding of how Lisp
quoting works.

That should work the same as his version, because (lambda ...) is a macro
invocation that expands into '(lambda ...).
