"Lisp" still hasn't; it is a family which comprises various dialects, many of which have lexical scoping, but some of which don't, like Emacs Lisp (which only had dynamic binding until recently and now supports lexical scoping, but not by default).
My comment was directed at the quote about higher-order functions, which is a more legitimately surprising thing than something about scope. And of course we're talking about whatever would have been considered "Lisp" by Appel in 1992, even though you and I might know better and be more precise today.
