The distributor doesn't care which wire begins the firing order sequence. It fires one spark plug every 45 degrees no matter what. Way back in the early days of the 265 V8 the distributor housing had to be clocked a specific way because a flat spot in the housing had to line up with an oil passage to supply oil to the passenger's side valve lifters. That got changed about 1958 or so when they put a full-circle groove in the housing to route the oil to the lifter gallery.
