It doesn't. The end quote with a period inside it ends the sentence.

There aren't. English doesn't nest or overlap sentences. Ever. Therr are plenty of ways in which English combines multiple units which each could otherwise be their own sentences into more complex sentences, but none of them involve having something which remains a sentence inside a longer sentence.
> The end quote with a period inside it ends the sentence.
What a weird interpretation. Two characters shouldn't be needed to end a sentence, only a period can end a sentence. It'd be a lot easier to postulate the period inside ends the sentence and the quotation mark ends the quote that just ran outside the end of the sentence by one character.
