More on expectations higher than expected

After reading my post on the ET article mentioning “expected to see a higher than expected rise“, a certain CA gold-medallist friend of mine wrote back this obscure note that I refuse to understand:

… if you take it literally it is not possible. To put it more technically, something called a law of iterated expectation comes to play. Today’s expectation of tomorrow’s expectation about what will happen day after is just today’s expectation of what will happen day after.

I think what they mean by “…” is that the revised expectation is higher than the earlier expectation.

She is in the habit of being right, so I had better accede.
