If President Ahmadinejad changes his mind on nuclear development is that a flip-flop?

BBC ran this article

In short, it says the Iranian President changed his mind is open to nuclear talks, the day after saying he would not budge one iota on the issue. If good leaders don't flip flop, then doesn' such a sudden change make him a bad leader? of course, that is what we want him to do....

Of course, there really isn't a change, it is more to ensure "deadlock" according to the article. No flip-flops for Pres. Ahmadinejad, just hardline positions. Kind of like our non flip-flopping President.
