Not that it saves any kernel dumps at least.. But otoh I have > no clue why it It means exactly that. IIRC kernel dumps are created in swap space and on the next boot are moved to ${dumpdir}. I'm pretty certain this is explained nicely in the handbook[1]. AFAIK kernels can only be dumped on real devices, not on virtual devices like /dev/mirror/*. In that case your setup is not going to get you any dumps. Besides that, it is probably not a very good idea to mirror your swap. I am certain it is bad for performance, if it'd gain you reliability is beyond my knowledge. This has been discussed before, you probably want to check the archives.
