I think this is if you're using the ZFS-install path of the installer. 
I used to do this custom (e.g. dedicated partition on drive with 
gmirror), not sure what you get when you go this path through the installer:

https://docs.freebsd.org/en/books/handbook/bsdinstall/

ZFS Partitioning Menu

* Mirror Swap? - Whether to mirror the swap between the disks. Be aware 
that enabling mirror swap will break crash dumps. Press the Enter key to 
activate it or not.

Wish I could give you more detail.
