No; this is for different use. The open and close are to open the Boot partitions part of eMMC 4; by default those eMMC will be using the user partitions, not the boot area. The nice, and confusing thing, is that those boot partitions also start in address 0 as a 'virtual disk'. -- Otavio Salvador O.S.
