Yes, it's hilarious. Severely limits the usability of the device, doesn't it? :-) > Huh?

I guess they say "might occur" either because that had several customers complaining about something like this or because they looked at the blueprint and could see some problems with isolation or something. Generally you can use the RPS the way you describe. Several people, including me, have been doing it with success e.g. when servicing UPS devices. Beware of the possible problems when trying to switch away from the RPS after the switch starts using it.
