no to be confused with the 'bung hole'..
what seems odd to me is that they needed to label it, whomever was installing the poles would surely know it was a 'cant hole' and what to do with it...I drilled a hell of alot of holes in wooden poles myself, and we never labeled any of them
thanks for disclosing your piss spot, I'll be sure to watch my step should I be in the area
