Yeah it's correct but with that tutorial there's no way /home or mmcblk0p2 was ever touched at all... Maybe you accidentally mistyped something? I could return back your original partition table but I don't know if ever /home will be able to remount properly(in short its a gamble).

I have no idea what will genfstab would do after rebooting.
Cause when you do the fdisk step above there's only 2 results...
1. You'll be stuck on an endless reboot loop(no choice but to reflash)
2. genfstab.awk would remount your MyDocs and /home properly.

So I don't know what's your decision here
