One important side-effect of a an author providing data and code, even though it is only good for re-analysis, is that it provides completely unambiguous documentation for what the original author "did". For example, if the original paper made a critical mistake, then there is no point is carrying out a replication, it won't work anyway. The Reinhart and Rogoff paper is a great example of this. We really should require that ALL papers in ALL disciplines allow for re-analysis, it is basically like an extended, and ongoing peer review process.
