It should work correctly as long as the help buffer is shown in one
window only.  It might fail when you show the help buffer in multiple
windows because `view-return-to-alist' is buffer-local.

We could set up a window-local equivalent of `view-return-to-alist' and
every time one quits or otherwise replaces the buffer, the previous,
explicitly placed there, buffer would get restored together with its
window-point and maybe other window-related/buffer-local information.

Alternatively, we could save the current window configuration when
invoking help or gnus and restore that configuration when quitting.
Personally I find this behavior annoying because it also destroys all
other changes in the window configuration I have done in the meantime.
A typical case is the backtrace buffer where I sometimes wind up
investigating the cause of an error in other windows.  When I eventually
decide to quit backtrace, all those new windows get killed too, leaving
me with a configuration I neither want nor need at that time.
