You are confusing \` with `.  ` is (obviously) treated specially by the
Lisp reader and converted into a form involving the macro \`.  At some
point in the past, this rather used the macro backquote instead.  If
this were still so, you probably would be less confused.  The connection
between ` and \` is arbitrary, and established by the Lisp reader.

M-: '`(+ 4 ,soup)

gives

(\` (+ 4 (\, soup)))
