In answer to the question posed:
Can you think of a real-world example using bidirectional links?

One example could be running the diamond on the baseball field. Normally runners go unidirectionally from batting box to first base, second, third, and home. However, a runner may be caught between bases due to a popup fly requiring to return or tag up on previous base or needing to return to a previous base due to another runner who cannot advance. Sometimes bidirectional movement is required - so previous link would help here.
