I think it is a mistake to not take the turn situation fully into account for the repetition rule. For one, it is illogical: we do condider the same board position not a repetition of the other player is on move. Game-theoretically a position is different when the side to move can still make a double move, or must do his second move. So why consider them the same?
In general it is bad to declare draws through an artificial arbitrary rule in positions that could be won without that rule. It seems not far fetched at all that a position is vastly better when you can do a two-move turn. E.g. the first move could discover a Bishop attack on the Queen, which you then take with the second move.
