Isn't Triplemania this weekend? Was it pre-taped? I'm not 100% on Mexico COVID regulations, but it seems odd that Omega can wrestle Friday for Rampage and then wrestle in Mexico Sunday for Triplemania. I assumed there would be some kind of quarantine situation.
I think with Omega v. Christian they wanted to load up the first episode of Rampage. WWE did something similar when the first weekly Smackdown happened and they did HHH/Rock for the championship. They want to go big for their debut.
