From what I understand you want to know: Phase A in one location is Phase A in another.. same for Phase B and Phase C?
If so the answer is yes ( as far as I know), that is if its all part of the same power system (grid)and most likely it is.. Phase "A" will not just change and be Phase "C" somewhere else along the line.. If that were the case it would cause mass confusion should the utilities try to so some switching of their lines..
Mind you if you are talking two entirely different power systems or supplies, they could be both rotating the same way but out of sync, or at worst rotating in opposite directions.. The only time that would come into play is if you are trying to paralell another generator onto the grid or into a local power system..
