The black tape either on the pole or the flag itself represents there is an alternative option. There is no shame in taking the alternative route, they are even provided at 4* like here at Badminton.
When walking your course even if you are sat on an XC machine walk the alternatives. You never know what may happen that may require you to jump it so make sure you walk it. You may miss your line slip on the turn or similar which means its safer and sensible to take the alternative at the last moment. Walk it properly so you can ensure you know where you’re going even if you have a split second to make the decision on which way you go. If you do make a last minute decision to go to the alternative route make sure to let the fence judge know by shouting ‘going long’ this will prevent the avoidance of doubt and potentially avoid 20 penalties,
