The port naming thing has some nuances that are not immediately apparent.
The first and biggest (for me) is that once you name ports you have to save that preset. Port names are tied to presets, not global.
One reason that the name is still there when you change away is to make assigning the name to an input and output port pair a bit easier. Often, an I/O pair is connected to the same device, so this saves you from retyping if you create the label for Input, then select the Output and reuse the name.
