No... if you update OFW, you source the firmware from your own emmc. Dump it with Goldleaf, then use daybreak in emummc. That site is useful for those who don't want to update OFW or who can't because their console is banned.You update via Nintendo server for OFW, as for CFW, Sysnand and OFW share the same NAND, unless you use an emunand, then you probably don't have a clean NAND, as for Emunand firmware update you use daybreak, and source your firmware like from that darthsternie site.
