Well those are his modified upgrade instructions, they seem relatively sound
but the extra steps aren't required.  The gpart stuff is to update the boot
loader which is only necessary if you upgrade the file system or pool eg
zfs/zpool upgrade.  You should probably run this just to prevent potential
severe pain later.

And as it's said, the nextboot is there because he's running a custom kernel
and wants to boot into GENERIC next time then later rebuilds his custom
kernel.

The short story is if you are running GENERIC anyway, a standard binary
upgrade would work fine, but if you have taken a divergent path you'll have
to account for those differences in your upgrade process.
