Well, the difference is that there's no whiteboard. If you're reading code off a whiteboard, you can shorthand over obvious things like brackets and indentation and whatnot, whereas trying to get a listener to picture a piece of code just by verbally describing it would take a lot more. I agree with your conclusion in the other comment that a lot of code would become unwieldy, but small snippets here and there are ok.

For sure. I can't judge what a listener would grasp since I do have the text in front of me, but at least the code is mercifully short.
