I think you'd be surprised. Though the problem isn't that it's hard to follow in the general case, but that things could potentially slip through the cracks.

Corporations are risk averse, they don't want to have to deal with potentially getting sued if a job opening starts out in one area and then moves to another one where suddenly the way the opening is described is illegal.

It's just easier to do it the same everywhere if the advantage they're giving up is small.
