Agreed. They behave differently and I touched on the differences in length.

Didn't intend that to sound as snippy as it does, sorry...but, the problem has much to do with the differences between elastic and inelastic collisions which is why I pointed out at the beginning of the subthread you really don't want to get too deeply into the actual physics because it isn't a trivial problem that can be correctly modeled with only a couple of masses with linear springs. Hence trying to draw conclusions on comparison to that as a model isn't fruitful.
While the example video shows an interaction between to solid objects w/o the inner mass of the deadblow hammer, the difference between the two shows the fundamental difference in momentum transfer between (nearly) elastic and inelastic collisions. Therein is the key to the difference in behaviors in the other as well altho it's yet more complex to actually model given the second mass. But, for a first approximation, think of the inelastic case in the video as if that were the impacting interior mass of the deadblow hammer assuming you could deliver the blow w/o the container and you've got the start of a visualization.

No. Correct conclusions and efficiently in depth.
