He's right that the probability of randomly lining up 150 amino acids into a functioning protein is vanishingly small - this is the steep front of Mount Improbable. The back of Mount Improbable in this example would consist of a functional protein made of 149 amino acids, another made of 148, etc, all the way down to functional proteins made of just a few amino acids - each of which can be hit upon by natural selection in the vast amounts of time available.

We'll probably never know every intermediate protein that lead to a particular modern protein, just as we'll never have a complete fossil record showing every intermediate step from the origin of life to us. ID proponents that jump on these limitations to our knowledge are just making the same old God of the Gaps argument.
