I think the author makes the distinction in the beginning.
> In experimental sciences, the experiment is the “real work” and the paper is just a description of it. But in math, the paper, itself, is the “real work”.
In other words, there is no replication crisis in math because there is no replication to be done. There is no experiment to be replicated, just work to be checked for correctness.
