On his episode of Guitar Villains, Jason Richardson basically said there's shit he's written that he can't always play because he hasn't maintained practicing it. That's the answer. Practice until you don't have to think about it. Until if feels the same to play on both.
Off topic but the level of practice he would have to constantly keep up to be able to play his songs live is insane. If he lets his technique or stamina slack slightly his live show could fall apart. especially since he’s writing even more technically demanding music now.
