That's because he apparently only knows about syntax-rule and not
syntax-case.  Look for the word "hygienic" in chapter 3 of his book:

"It is no wonder that the Scheme designers have experimented with
so-called hygienic macro systems to avoid having to type gensym all
over the place. The wrong turn that Scheme took was to promote a
domain specific language for the purpose of macro construction. While
Scheme's mini-language is undeniably powerful, it misses the entire
point of macros: macros are great because they are written in lisp,
not some dumbed down pre-processor language."
