I think this is a good example. The "hot" and "cold" labels you can find in a bathroom describe what flows there. It happens that there is exactly one port with each kind of content, so there is no ambiguity. But if a boiler has several in and out ports, several of them might give or take cold water, and several of them can give or take hot water. The name is not relevant, even if in simple cases, when you have only one port of a given type, the name can be the same; what really matters is the nature of what flows through. Sometimes you want to give a more explicit name (e.g. if you have several "cold water" ports), but you want to give the ability to connect automatically the primary one, the one port that makes more sense to connect to by default when you have another "thing" that have a "cold water" port.
