I think there are a number of possible reasons for all the "topping and tailing" that goes on nowadays.
1. No runround loops at many stations.
2. Where runround facilities do exist, qualified staff would be needed to couple/uncouple the loco.
3. Having an extra loco is beneficial in the event of a failure.
