If you have a live standby database you cannot shut it down to take a backup then bring it back up and expect everything to be all honkey dorie. If you were to do so, any changes that prod shipped over to you via redo or archive would not be able to be applied.
So what? All changes will be applied once the standby is up again and everything will be just honkey dorie, no? Nothing lost, no harm done.
