genesis bitcoin mining and BIP148

So i own an open ended bitcoin mining contract through genesis and was concerned about what might happen with my contract and/or payouts before during and after if Bitcoin were to split. You know i haven't made all of my money back yet so I've been alittle concerned about the affects of this scenario. So i emailed Genesis and they responded:

There are several proposals for Bitcoin scaling, as you know. Right now it is unclear which one will make it through, but whichever it is, we will follow and your hash rate will keep on mining. We will have more info through our blog pages very soon.

So even though this answered part of my question it still leaves me wondering what would happen with payouts if there ended up being two bitcoins...
