I think Rellim meant going from Wrestle Kingdom to the WrestleMania that's a few months later, whereas Cody was at WM and then did next year's WK. Still technically within 12 months, but not what I think he meant.
Although, didn't AJ Styles do that? WK 2016 followed by WM 2016. Ironically, with the latter being against Jericho.
