I think you are reading too much into this, it is a common sense statement.

The example is there is a bet in front of you you have 3 descision call, raise or fold. Calling is "unprofitable" meaning you will lose money in the long run, and Raising is "unprofitable". That is the scenario, you have to figure out that it is "unprofitable" and as you state about a draw, a draw is "unprofitable" when the pot-odds don't work if the pot out or even implied odds won't be profitable, if they worked out it would be profitable! It doesn't matter limit or no limit. And while you won't win money in the long run by folding, you save your money. By being unprofitable you lose money in the long run. There is no reason to overthink that, because it is just a point. So no there is no error in that statement.
