Ok, I think I understand it now. So he has 2 devices, a new one (m8) and an old one (Nexus). He wanted to play his account on both (His main village is on his old device). However, instead of signing into G+ on his main account first! he signed into it on his second so now the very low level village is synced with G+. To play on both doesn't he just have to make a new G+, sign into it on his main account then sign into it on his second?
