you can't know that. I've seen people fold in these situations. You might be 99.999% confident, but you never 'know'. He could have a heart attack at the table and die and then his money doesn't go in! I know I'm getting ridiculous here, but if the money is not actually in the pot, then it is implied odds, however high the likelihood that it will go all in.

Lets say the flop came AKQsuited and he is sitting there with pocket 9's? He might fold there - I've seen players do it.

Or what if he was actually making a squeeze play with two crap cards?

As I say, until he has actually put it in, it is implied odds. In this case for practical purposes though, there isn't much difference - it is more than reasonable to assume that all the chips WILL go in, so you do your calculations as if they were all in NOW.
