Hi Speakerguy,
this method has just one minor advantage. If you name the pin you won't have the pad number on the schematic, which is normally used for trouble shooting. Doing that with the pin describtion requires a datasheet of the chip to know where you have to put your probe.
I prefer having both info of the device, pin name and pad name (number).To indicate an inverted input or output I use 0.12mm thickness and draw a horizontal line above the text using 0.635mm grid size and letter size of 1.4224 mm using the names layer. To make it look better I switch to grid size 0.3175 when everything is done and adjust the line length to the actual text length.
