It's used to figure out which way to print pin names/numbers in pcb
when you ask for them to be displayed, that's all.

It's just a mnemonic name: EP == exposed pad

Pin "numbers" can be non-numeric.  The difference between names and
numbers, is that importing a schematic will overwrite the names based
on the corresponding pinlabels in the schematic.  But the netlister
can handle pin *numbers* like A4 as BGAs use that numbering pattern.
