I realize this is old. I've noticed wherever I start using the ehsd or any of the other sss displays they stay. I like them on the right because, if you think about it, the point of the sss is to create some hands off functionality and let me use my right hand, throttle hand to quickly do things and still fly the aircraft. I don't have to use those sss pages manually, leaving my ew, stores, and vref pages on my right, easier to access.
I don't know how it is supposed to be in real life, but that's my feelings on it.
