Only lower drawing is RLM system, the one above is regular LM. The biggest problem with RLM is that it wastes column length, been there done that and it is very difficult to fit a needle valve and all the needed connectors and piping under 100mm of column length. In practice you also need a product condenser and at that point it would be easier to build a VM system where the vapor is condensed directly in the product consender giving slight edge on purity.
