I actually believe this is probably the case. Watching MKBHD's ride on YT indicated they replaced the glass prior to riding the press around, so they probably had this planned in advanced to some extent.

I don't think anyone should have realistic expectations of the outer layer of glass not shattering. That is why there are multiple layers. If you threw a big metal ball really hard at the president's limo, it would likely crack the outer layer as well in similar ways. What fundamentally controls the strength of armored glass is how many layers you have.
