That means sysupgrade upgrades the current boot partition.

But is that any different than the images from @clayface ?

the difference is that there are a number of files like upgrade.sh and bootcount that on sysupgrade switch the active partion; also there is a script to setup uboot to switch the alternate partition. do a diff between the two repos and you will see ... also there is a discussion on this forum on this topic probably a couple of months ago ...
