That does not really matter I think. The cool part is that they very able to build a cube that looks similar like Rubik's but has electronics and motors embedded that are able to turn it.
Solving the cube with a computer is a solved problem for a long time and there are myriads of algorithms. Granted the solutions are not perfect (i.e. using the minimum number of steps needed which is always <= 20), but mostly come close (~25 steps).
