I don't think there's mixing, but normal Multipoint keeps both connections alive, and switches to whichever has active audio coming. It can be a little annoying if you have notification sound on your phone stealing the attention, but generally it works pretty well.

But again, simple multipoint support seems to be pretty rare. I think the newest WH-1000X M4 finally added it, the Microsoft Surface headphones also have really good ones, and that's kinda it.

Some devices like Samsung instead use a fast switch, I think that's what Apple is doing here too?
