multilang rom in system 2, so old rom in system 1?

May 23, 2014
Hey guys, just updated my phone to the multilang rom a week ago, have been playing round with themes etc. rebooted to recovery to clear cache just before and noticed when i entered reboot, system two was highlighted as latest (multilang). question is, does this mean i can use dual boot and use Singapore stable rom (my previous rom) simply by booting into recovery and selecting system one? and then switch back to multilang rom anytime?
