I like live coding too but I think how much of it is acceptable depends on what you're trying to demonstrate. If you're doing a programming tutorial video then yes by all means type every line so the viewer can follow along. However, if you're trying to show how various code changes get reflected in your browser do you really need to dedicate 20% of your video time to writing a sine function?

I think so, especially in this case. In this case, you only really get a sense of just how interactive the programming is by watching how a really short amount of time coding produces game play changes. When people cut and paste I think the viewer wonders in the back of their mind if something else got tweaked (not intentionally to mislead or anything, but because of the nature of coding). This is probably one of the reasons why, for example, the PeepCode Play by Play videos got so popular.
