I don't use mmm-mode so I don't know what assumptions it makes or how it
works.  But when I find a latex file with contents

--8<---------------cut here---------------start------------->8---
documentation chunk
<<*>>=
a = 'a'
@
documentation chunk
--8<---------------cut here---------------end--------------->8---

using AUCTeX 11.88.7, only the <<*>> is highlighted in
`font-latex-string-face'.  I don't have the effect that everything after
the second ' in 'a' is fontified with the `font-latex-verbatim-face'.

Do you have any customizations that affect verbatim highlighting?

If you want, you can use AUCTeX also with the usual font-lock rules
provided by the built-in tex-mode instead of the more powerful
font-latex.  To do so, put

  (setq TeX-install-font-lock #'tex-font-setup)

into your ~/.emacs.
