The argument that there is no trend seems to make sense to me. We are not told about the complexity of the hypothesis, what we are told is both H' and H contain a set of hypothesis functions which can be simple or complex.

I disagree with the assertion that fewer alternatives means less options and less complexity. A hypothesis set may have a few number of possible hypothesis functions but one of those functions can have the complexity to provide a good fit. Hence, less deterministic noise.
