It does?  I see this:

    (cl-loop for file in command-line-args-left
             if (or (null byte+native-compile)
                    (cl-notany (lambda (re) (string-match re file))
                               native-comp-bootstrap-deny-list))
             collect (comp--native-compile file)  <<<<<<<<<<<<<<<<<<<<<<
             else
             collect (byte-compile-file file))))

What did I miss?
