ITU-1770 -24LKFS and -10dBTP

I'm finding a couple broadcasters are asking for -24LKFS or -23LUFS and peak levels of -10dbTP. I can understand this on stereo mixes that might be using an analogue broadcast in some countries but I thought the only way to broadcast a discrete 5.1 signal is digitally. In that case shouldn't they be able to accept a 5.1 mix that is -2dBTP? There are two broadcasters I'm dealing with that insist there spec is ITU-1770-3 but to be sure their peak is -10dBTP for 5.1 and stereo. Does anyone have any idea why this might be?
