from the looks of it it was supposed to be one of those 'both went through at the same time' questionable endings, except sheamus' table didn't break. therefore by match rules, he wins.
Looks like it was supposed to be one of those "who went through first?" like with the cage escapes or the rumble. Would be pretty funny if Sheamus was just thought, "screw it im supposed to win anyways im not taking a blind fall through this crap"
