FreeBSD UEFI and freebsd-boot second partition

Sorry, just failed to find this after a quick googling: bsdinstall in 
UEFI environment creates freebsd-boot second partition. What for and 
what lives there ? I used to think that only EFI system partition is needed.

P.S. Attached a second disk to zroot and now wonder what to put there. 
Should I treat it as the regular pre-UEFI gptzfsboot one ?
