You misunderstand it. The situation of concern is where the 400 year period governed by a rule is immediately preceded by something that is *different from* what the rule would have. If the preceding DST behaviour has transitions later in the year than the transitions produced by the rule, the last preceding transitions could occur less than 400 years before the last rule-generated transition that zic puts in the output.
Why not put a non-transition (i.e. a transition to the same offset already in effect) at the beginning and end of the 400 year period?
