`font-lock-mode' is not so useful for the fontification of Help buffers,
so it makes sense not to use it. For highlighting regexps, as in your
examples, hi-lock is just fine. *Help* is mostly text, not code.
OTOH the code could be easily rewritten to use font-lock-mode and
propertize via the font-lock-face text property. I guess the reason for
that this is not the case is just that *Help* is much older than
font-lock-face, and nobody yet wanted/needed/requested to use
font-lock-mode in *Help*.
Michael.
