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.
