For hibernate, the ram-based swap of course should be bypassed.
It's worse than that. Memory belonging to the ram-based swap medium would be marked as not itself swappable. Otherwise, you would get in a loop. So, it has to back itself up to its private backing store device before hibernating, and restore itself before the OS is allowed to resume. It can't just stand by and passively allow another swap device to take care of its pages.
