Hi,
Thanks for the question.
Actually, the shuffling operation here is preparing the data for the random sampling in this line. If we do not perform shuffling, then the sampling will not be random.
As for the scatter operation later, it has no relationship with the shuffling operation above. The above shuffling is done at the point level. Later the randomly sampled points will be converted to voxel by scatter operation.
If you have further confusion, feel free to continue this discussion.
