Basically he's trying to say "Each of the 3 questions must be unique and only asked to a single god, and each god can receive 0, 1, 2 or all 3 questions out of the 3 unique questions". In other words, don't create 1 question and ask it to multiple gods. But if you create 2 or 3 different questions, it's fine to ask them to the same god (forgoing to opportunity to ask them to another god).
