I think I tried to say the same thing in the text you quoted.
I tried to imagine a block of the same mass, but very long in one direction, so as it would have a considerable moment of inertia. Let L be the off-center distance along that direction, that the bullet hits the block.
As you wrote, the equation Eo=DE+PE+RE always holds. And also Eo and PE are always constant, regardless of L. Thus DE+RE=Constant
While L varies from 0 to Lmax, there is a transfer of energy from DE to RE. As L grows, I expect DE to fall.
I also imagine that if it wasn't for the error margin of the measurements, we could observe the decline of DE as a function of L, as L increases.
