The *Help* history doesn't save the actual text in the buffer, but
regenerates it based on the parameters given -- so if you go back to the
documentation for, say `describe-mode', it'll regenerate the buffer
based on the current documentation for that command.  This also means
that if you change the documentation (loading a new version, for
instance), you'll get the new version of the doc string, and not the old
one.

So this is working as intended, and I'm closing this bug report.
