Not exactly true - they are "entitled to advance without liability to be put out". There is a subtle difference, and this difference comes into play in the scenario we are discussing. They MUST still advance. They cannot be put out while advancing - but they can be out for failing to advance (or for missing a base and continuing to advance).
