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.
[1] Which I didn't check as I'm about to be in a hurry...
