I don't know. Earliest leaks implied that Ren did survive and ended up living with Rey on Tatooine, so maybe the reshoots were to make him die since we can't have a perfect Sue like Rey needing a man in her life. We can't have THE FORCE GODDESS be weighed down by a man.

The Force is Female. Not a couple.
In seriousness though, the reshoots ended about 2 or 3 weeks ago, and all the most recent shit indicates that Kylo Ren dies, but for all we know, there probably is a cut of them together in a corny romantic ending. And if Reylo happens, Disney shits will defend this trash to infinity and beyond. But if it doesn't happen, we'll have a few more useful idiots for the anti-Disney Wars crowd.
