Yep, it is probably one of those things that was set in concrete and never changed. But it really doesn't matter how you want to do it as long as Mark is the higher RF frequency, since that is the frequency you give as your operating frequency for RTTY. Now programs like MixW allow you to stay on USB if you want. If you have to set your rig for lower sideband, it has that option too.
