I FIGURED IT OUT!!!
Okay, sooo let me explain how it works...
YMX (or MX I forgot who said it, but...) You can't change the events that happen in time right? So there is no "Alternate timeline"
SoD didn't go back to ask YMX to turn to darkness, or anything that changed him (at all) what SoD told YMX was about the plans they had
So what happened is this: Normal timeline occurs, SoD travels back in time and tells YMX about the plans, again, normal timeline continues and everything happens

I might be jumping around on my points (probably not explaining it as well as I could) but let me know what you guys think
