line direction in geometric networks?

I am currently investigating ways to model flow in our drainage network using ESRI tools. I have successfully set up a geometric network using our drainage pits and pipes, set sources and sinks as well as flow direction and modelled this using the ???Utility Network Analyst??? tool.

My specific question is: Does line direction within the network need to be set to correspond to flow direction, or is it sufficient to just set up your network with sources and sinks to indicate flow?

My reason for asking is that I have found a number of scripts through the ESRI user forum which can flip lines to match flow direction and I was curious to know if there was a specific reason why people may perform this task?

Cheers,
