All that would prove is that the the code that implements a buggy version of a model gives consistently wrong results. Actual replication requires that somebody else implements the code independently. And that both implementations are checked over a reasonably wide range of parameters over which the model should be valid. Actual replication is much more effort and consequently slower than just a "docker run".
