Sorry, it's another game sharing question!

Hey. I know the basics of game sharing but couldn't see this question brought up when I searched. Basically I've had an Xbox since day one and have some 200 digital games. I'm after picking up a One S over Christmas so gave my Day One console to my brother as a gift. As he doesn't have any games I was going to leave that console as my home one, and set up my One S as a secondary console so he could play my games. The only question I have is relating to my girlfriend. She has a profile that she's always played my games on with no issue. If I set both my profile and her profile up on my One S but leave the Day One as the home console, will she still be able to play my games, or will she be locked out as the One S isn't my home console?

I'm really hoping not, as I'd like to gift my brother access to the games, but I don't want to cut my girlfriend off so to speak. Hope that made sense.

To complicate things the One S is sitting in a box in Sweden where I live, while I'm at home in Ireland with my Day One. So I can't just test it out, I need to wait until I get back to Sweden next week. I'm hoping to know before I head back. Basically I'm wondering if anybody who game shares can tell me if other profiles can still access their games on the console that isn't their home console?
