That's pretty odd.
Digging through the ChangeLogs, this is apparently the commit that
added them, but it doesn't say why.
1999-01-11 Richard Stallman <rms@psilocin.ai.mit.edu>
* help.el (help-mode-finish): Renamed from help-mode-maybe.
Don't switch to Help mode here.
(temp-buffer-setup-hook): Use help-mode-finish.
(help-mode-setup): New function.
(temp-buffer-setup-hook): Use help-mode-setup.
Richard, why is `help-mode-setup' run in absolutely all
`with-output-to-temp-buffer' buffers? This seems rather un-optimal,
since that macro is used for many other things than showing help
buffers.
