Now, I will first admit to being a novice to bedding and regulation in
general (although I'm getting better) but I've played a few games of
pool/billiards in my day.  If I were to guess at what's happening, I
would say that the energy of the hammer checking is being dissipated
not just down through the keybed and into the frame, but also out
along that nice hard balance rail and into adjacent keys.  Just like a
line of billiards balls or a newton's cradle[1].

This would be just a guess, however.
