Any downside to letting a KW agent refer me for recruitment?

[Shawn Regnier]

Hi, I'll be taking my RE exam next week, so if/when (I feel confident it will be "when") I pass I will need to hook up with a broker. After many hours of researching and asking questions on BP, I've decided Keller Williams would be my best bet; due to their incredible training system for newbies.

I told one of my client's (non real estate client) which office I was interested in, and they knew an agent that had worked there previously. That agent told my client to tell me to ask for "such and such" at the office, and to let him know that "such and such" sent me. 

I know there's some kind of profit sharing in KW, but I'm not really familiar with how it works; all I've been doing is studying for my exam. If I drop the name of Agent "such and such" will there be any cut taken out of my commission on future sales, and given to the agent that said to give them the referral?

Sorry for what probably sounds to you all as a silly question, I'd just like to understand how referral/recruitment works; if that's even a thing in KW.
