Nope, analogy fail. The meaning is absolutely different. If someone says to you "She took how much of your money?", and you reply "I didn't say she stole my money" that means something completely different than "I didn't say she stole my money". Who the pronoun refers to is completely external to the parsing of the sentence.
No, they meanings are really the same. You're telling the person that you did not do something. That something, no matter which word you stress, is the acting of saying she stole your money.
