I guarantee it is precisely that, the same tree. For so long the mantra in the bonsai comunity was that you cannot develop a bonsai from nursery material. I, having no choice other than seed or nothing, have chosen to use the nursery trade for my material. As you can see, trees in confinement can develop in amazing ways, just like trees in nature confined in poor environments and limited space grow and impart interesting traits.
The catch with nursery material is that it usually needs to develop for a while to become even good pre-bonsai. Many people seem to have neither the vision nor the patience for that project. I love finding decent nursery material that still needs work. It means that I can influence how it matures over the next 5-10 years. That's an opportunity you just don't always get with already-mature or developed trees.
