This simple exercise is more than just a trapping of mutualistic discourse. It actually forces you to think about their point, and leads to a greater understanding of what they are trying to say... which, in turn, allows you to waste less time by explaining a counterpoint to an argument that they didn't make. I try to make myself do this even when I'm not arguing with someone. If a task comes to me from my boss, I will do my best to rephrase it in my own words (not verbatim, unless it's something really simple) to make sure we're on the same page.
