This will significantly bias the second study towards getting the same result. Providing help and assistance beyond the paper itself will create experimental controls that are undocumented - assumptions that were shared between researchers but not published in the papers themselves, because humans are bad at that. Further, giving any sort of relationship between the experimenter and the reproducer will taint them - people are friendly and want to see their friends "succeed" - they will taint their own work out of empathy.
