He’s still not saying what he meant by refined and it’s surprising that he doesn’t get that he has to be careful in choosing his words. His position means something and he can’t be imprecise and keep people guessing. If he’s shifting positions, the voters have a right to know:

“For me to say that I’m going to refine my policies I don’t think in any way is inconsistent with prior statements and doesn’t change my strategic view that this war has to end and that I’m going to end it as president,” Obama told reporters on his campaign plane.

“I was a little puzzled by the frenzy that I set off with what I thought was a pretty innocuous statement,” he said on a flight from Montana to St. Louis. “I am absolutely committed to ending the war. I will call my joint chiefs of staff in and give them a new assignment and that is to end the war.”
[…]
“I’m surprised at how finely calibrated every single word was measured. I wasn’t saying anything I hadn’t said before, that I didn’t say a year ago or when I was a United States senator,”
[…]
“The tactics of how we ensure our troops are safe as we pull out, how we execute the withdrawal — those are things that are all based on facts and conditions,” he said.
“I’m not somebody who, like George Bush, is willing to ignore facts on the basis of my preconceived notions. I want to pay attention to what is happening on the ground.”

Um…did Obama resign from the Senate? 🙂
Isn’t his preconceived notion that he has to remove troops from the ground and end the war? But what if he goes to Iraq, talks to the people who actually know what’s going on over there and discovers that pulling troops is dangerous to the Iraqis and our soldiers, what then? Does he still go through with his plan to remove troops despite the risk? How is that different from what he’s accusing Bush of doing?
I agree with McCain’s spokesman:

“What’s really puzzling is that Barack Obama still doesn’t understand that his words matter,” said McCain spokesman Tucker Bounds.

You’d think that a man who makes such a big to do over words in his “Just Words” shtick would understand the importance of word choices when speaking to the press. I think his amazement demonstrates how green he really is.
