Deep in org-babel-tangle,
(org-babel-map-src-blocks nil (let ((i (let ((org-babel-current-src-block-location (point))) (org-babel-get-src-block-info 'light)))) (when (equal (or (cdr (assq :noweb-ref (nth 2 i))) (nth 4 i)) source-name) ...)))
So, while :noweb-ref gets priority over #+NAME, we can still accumulate blocks
having the same #+NAME (provided there's no overriding :noweb-ref).

Even though I'm a huge fan of this behavior, which lines up well with the
traditional WEB and Noweb behavior, the Org manual's discussion of code blocks
does say, "For duplicate names, Org mode's behavior is undefined." [Section
14.1] So,
Dear Org Maintainers,
Please do not change org-babel-tangle's accumulation behavior for duplicate
#+NAME's. It's handy, and users of other literate programming tools will find it
familiar. Also, #+NAME is a nicer per-block syntax than :noweb-ref.
Sincerely,
Kevin M. Stout
