That's true in some cases, but untrue often enough that I disagree. In my experience, interrupters frequently assume something entirely different from what was actually being said, or even cut off the speaker before a "but" and wind up responding to the exact opposite of the intended point. This is needlessly annoying and confusing to almost everyone involved.
