I look at the Burning Hammer kickout as meaning that Kendrick at 157# can't use it effectively against Ibushi at 189# (as JonnyLaw says above). I also considered the possibility that Ibushi's repaired neck is now bionic, giving him immunity to many head-dropping finishers, but I think that would need more & deeper setup to pay off.
Stepping back a level and getting more meta, though: maybe Kendrick's Burning Hammer, and the kickout, were meant for Daniel Bryan, as though they were a taste of the blowoff match that a top-of-his-game Kendrick would have had against a healthy champion Bryan.
