M4 Documentation:

This step selects only the negative training examples; these are the clients who have not churned. Therefore, during deployment this step does not filter out anything; the steps that deploy a learned decision tree are applied directly to its output, while the steps needed for training are applied to a subsample of its output. The subsample is necessary for training in order to reduce the class overweight of the negative examples.
