Because it didn't work.

(defvar foo-var 0)

(defmacro foo-mac ()
  '(setq foo-var (1+ foo-var)))

(define-obsolete-function-alias 'old-mac #'foo-mac "24.4")

(defun foo-fails ()
  (old-mac))

(defun foo-works ()
  (foo-mac))


Compile:
foo.el:13:4:Warning: the function `foo-mac' is not known to be defined.

Load compiled version:
(foo-fails) ; -> (invalid-function old-mac)


Also, neither version warns that old-mac is obsolete.

I see now that

(eval-and-compile
  (define-obsolete-function-alias 'old-mac #'foo-mac "24.4"))

works. So maybe that should happen automatically at top-level.
