John, I believe the root is very much alive because I dug it up from my garden just few minutes before I grafted, the tree has almost a foot of mulching of wood chips. Also, I did not planted them all, today I am preparing to plant one similar graft - the root is very healthy it has whitish points and has more crusting tips for more roots, these were in the moss box, but wrapped in newspaper. I believe if it was in dirt, the root would be bigger. Only time will tell. You could be right. the cutting could be doing what cuttings do. (however, its sibblings are not doing the same).
