You're right. But in the case of 'open papers', the person selling it is not the registered owner, so there's always a risk that the information on the open MTA6 will not match with what is with RMV. Best is to have it checked at RMV, but you will need some inside help for that. I've bought many vehicles on 'open papers' and never had a problem. But I know people who've had trouble with open papers. There's always a risk.
