There are sometime where your end condition will be different if certain roadway item existed. However, only one infinite end condition can be drawn in a template. Which for us users require creating multiple template for those different end condition where it behaves differently if roadway item exist.

With allowing multiple infinite end condition with IF statement significantly reduce the time need to develop multiple template. As using feature definitions to track existence of certain roadway item and if they exist execute end condition A and if does not exist execute end condition B.
