Perhaps, but they didn't really get into specifics. Your brain controls how you perceive and interact with everything. So it is somewhat easy to conclude that you brain is expecting to smell certain things. It has been stated many times that "the sense of smell is the strongest sense tied to memory."
If someone were to say is this rotten, and you have smelled(smelt?) the same thing before when it was rotten, you will already have a preconceived notion of what it would smell like.
The question is, are they saying that because you have a preconceived notion of how it would smell that it would automatically smell that way at first, or just that you can recall from memory what something smells like.
If it is the latter, IMO this article isn't stating much.
