Can someone give me a TLDR?

Just kidding - though I will say this type of behavior can sometimes fall somewhere between "Tricks to Sound Smarter at Meetings" and "what gives people feelings of power", so don't misuse it or misconstrue it being used on you as solely a positive force for understanding.

Two big takeaways (see? paraphrasing!):

Your tone should convey the desire to clarify and understand what the speaker said. If you don't have this desire, don't fake it.

“Studies in labor-management negotiations demonstrate that the time required to reach conflict resolution is cut in half when each negotiator agrees, before responding, to accurately repeat what the previous speaker had said.” - Marshall B. Rosenberg in Nonviolent Communication.

My tldr Paraphrasing saves time, which people value more than money.
