M4 Documentation:

In this step all rows that belong to the same transaction are merged by taking the maximum of the binary flag-attributes within one transaction. Thus, before this step, only one binary flag is set per row, because each row corresponds to one product sold in one transaction; after this step, several flags can be set, indicating all products sold in the complete transaction which is stored in a single row.
