Where and how a sentence containing a phrase is placed makes the biggest difference, and the emotional implication of the sentence altogether depends a lot on that. Putting it at the beginning of a sentence conveys immediate consent. When the clause is used at the end, you are somewhat unconvinced about the statement made by the other party. As such, your approval is always conditional. When a question mark is put at the end of an emotionally charged sentence, that entire sentence turns out to be a question. In that case, the speaker questions whether the other individual means what he or she says.
