Why does E3V6 gold fan have a Dupont connector on both sides?

I have a Reprap printer, but just bought a E3V6 gold extruder to mostly print more abrasive materials. Besides the nice features of the gold series, I noticed both the thermistor AND the heatsink fan has a Dupont connector on their ends. This is nice for easy replacement of these parts without having to rewire your entire extruder harness.

However both sides of these Dupont extension wires (one for thermistor and one for heatsink fan) have connectors added to them. Why would you have a connector on the other end of the heatsink fan? Isn't this always supposed to be attached directly to the power supply and not the board?

Answer this question I have this problem too

Is this a good question?

It gives you the option to plug the fan into the board, as many boards have a port specifically for the heat sink fan. If you'd prefer to splice into the power input of the board, or wire directly to the PSU, you can just cut off the connector. It's a lot easier for those who want to connect the fan to the board to have a connector.

Yes, I bought a Rumba board and found out how to program the fan output to turn on hot end fan when temp raises above 50 degrees. So I'm going to use it this way. I didn't like having it attached to power supply since tiny wires on large terminals.
