Halo 4 Free Gold After SR 50?

So about a year ago, I reached Spartan Rank 50 on Halo 4, right after that I got Xbox live gold for free. Can anyone tell me what happened. I did a post a while ago saying this but only one person replied sayin “impossibru”.

Same thing happened to me (kinda). It could just be that Xbox Live Free Multiplayer Weekend was on.
