This part of the getCoresetFromManager() function does not make sense to me either. Having looked a bit deeper, I am not sure that this behaviour is consistent with the original paper. It seems to me that the coreset should be computed from all of the non-empty buckets whenever it is needed so that the clustering produced makes use of the most recent instances.
This is one of the modifications I have made to MOA's StreamKM++ algorithm and made available on Github here.
