Another question about "the only"

Chipster Study

JY says you have the same subject in both parts of the sentence that has "the only." Ex. The only kids with green eyes are the ones with red shoes." But, what about this sentence. "The only way to New York is through Florida." Way to New York is not the same as through Florida???

S: if you're going to New York
N: you must go through Florida

NY --> Florida first

The same subject will not always be as obvious as in the first sentence. For the second one, you could say that the "way" or " a route" would be the subject addressed by both the sufficient and necessary conditions.
