He just lies to suit the mood at the time.
I'm beginning to understand it now. I believe what he meant was that, in matters of foreign affairs and strategies, the whole world would know his plans and timetables. In matters of political strategy, his lips would be sealed until he was ready to take action. His secret meetings with special interest groups right after being elected and his telegraphing of his punches during the middle eastern crisis have finally made clear what he really meant. I think he has confused transparency with opacity.
