images. Per hier(7), the ESP will be mounted at /boot/efi. On UFS systems, any existing ESP will be reused and mounted there; otherwise, a new one will be made. On ZFS systems, space for an ESP is allocated on all disks in the root pool, but only the partition actually used to boot is set up and mounted. This makes future upgrades of the EFI loader easier (upgrade scripts can just change /boot/efi) and also greatly simplifies the parts of the installer involved in initialization of the ESP. It also makes the installer's behavior correspond to the documentation in hier(7).
