It all depends how the dna you pass on is maintained and how sperm and eggs are replenished. If you can break an organisms stabilising regenerative means in such a way that effects the sperm or the egg then there is an effect on the next generation.
Imagine say you have an orchestra. they all roughly know what the other is doing. In order to stop that orchestra from rebuilding after lost personnel and playing there main theme tune you would have to remove quite a lot of personal (the cutting the tail issue). However this does not mean the orchestra can't play a slightly different theme after a long process of trying to help the members to play something more tweaked (the generational head binding issue).
head binding does not directly tweak any DNA. Using you orchestra analogy, head binding caused nothing that is the equivalent of of even a single orchestra member being lost, nor have the effect of causing any member to play differently then he/she had done before.
Stem cells can be manipulated either by mechanical and chemical means basic genetic science.
What affects drive genetic change relative to mechanical stem cell manipulation over generations is not a well researched topic only some old proof that regeneration through breeding has a degree of immunity to a damaged parent negatively impacting there offspring. We do know if we damage a worm bad enough it grows back the wrong half that's about as far as it goes.
I suggest they try being nice the worm and see what effects can be stimulated by mechanical means.
