Doesn't the first proposal have the problem that there is no 2:59:59 EST, the Eastern zone having changed to DST?

No, because the affected locations were observing EST without DST. It is a bit tricky, in that the "simpler" solution here relies on the fact that there's no DST before the change. The "more complicated" solution is a recipe that will work when the DOT makes more-typical changes, e.g., in North Dakota, which observes DST both before and after the change.
