This is due to the peculiarity of the implementation of
`Info-revert-find-node' that kills the *Info* buffer to revert it.
Its comment says:

  ;; It's perhaps a bit nasty to kill the *info* buffer to force a re-read,
  ;; but at least it keeps this routine (which is for makeinfo-buffer and
  ;; Info-revert-buffer-function) out of the way of normal operations.

It has other nasty effects when used in defcustom, e.g. when
*Info* buffers are displayed in different windows, it will mess up
the window configuration.  I think `Info-revert-find-node' should
be rewritten to not kill the *Info* buffer, but I'm not sure
whether this is need for 24.1.
