what that will give is *two* bootable Micro-SD card options, priority being first the external one (MMC0) and second the on-board one (MMC2).
I can't comment on the technical issues but I think this is an improvement in terms of usability, at least from my experience using other systems that relied on booting from Micro-SD instead of from NAND flash.
